Description

超声设备及其三维超声图像显示方法技术领域 Ultrasonic device and three-dimensional ultrasonic image display method thereof

[0001] 本发明涉及一种超声设备，具体涉及在超声设备上对三维超声图像进行显示的技术。 [0001] The present invention relates to an ultrasound apparatus, and in particular to a technique of displaying a three-dimensional ultrasound image on an ultrasound apparatus.

背景技术 Background technique

[0002] 在医学超声仪器的使用过程中，常常需要采集三维的体数据，形成体数据集，并对该体数据集进行渲染显示，以显示被测组织的三维超声图像。有些情况下，超声仪器还对该体数据进行区域的划分，例如从体数据中提取感兴趣对象或区域（如胎儿脸部等关键临床结构与部位），或者将体数据划分为多个分别对应不同感兴趣对象或区域的子集等，然后对各对象或区域进行渲染显示。不管是对三维超声图像进行渲染显示还是对各对象或区域进行渲染显示，现在医学超声仪器通常都是采用同一种渲染。这样的显示方式带来的问题是，当多个对象在某个视角上处于前后重叠吋，通常只对医生选择的感兴趣对象或区域进行渲染，这导致医生只能看到一个对象的细节，而不能同吋直观地看到多个对象的表现。 [0002] During the use of a medical ultrasound instrument, it is often necessary to acquire three-dimensional volume data, form a volume data set, and render the volume data set to display a three-dimensional ultrasound image of the measured tissue. In some cases, the ultrasound apparatus also divides the volume data into regions, for example, extracting objects or regions of interest (such as key clinical structures and parts such as fetal faces) from the volume data, or dividing the volume data into multiple corresponding correspondences. A subset of different objects or regions of interest, etc., and then rendered and displayed for each object or region. Whether it's rendering a 3D ultrasound image or rendering it for each object or region, medical ultrasound instruments now typically use the same rendering. The problem with such a display method is that when multiple objects are overlapped at a certain angle of view, usually only the object or region of interest selected by the doctor is rendered, which causes the doctor to see only the details of one object. It is not possible to visually see the performance of multiple objects.

技术问题 technical problem

[0003] 本申请提供一种超声设备及其三维超声图像显示方法，使得医生在显示界面上可直观地同吋看到多个对象的渲染图像。 [0003] The present application provides an ultrasound apparatus and a three-dimensional ultrasound image display method thereof, so that a doctor can visually see a rendered image of a plurality of objects on a display interface.

[0074] 根据被测对象特征从超声三维体数据中采用图像处理和 /或图像分割算法检测一个或多个被测对象特征的位置，根据被测对象特征的位置确定归属于被测对象的三维体数据，这些三维体数据组合该被测对象的子集。 [0074] detecting, by using an image processing and/or an image segmentation algorithm, the position of the one or more measured object features from the ultrasonic three-dimensional volume data according to the measured object feature, and determining the three-dimensional belonging to the measured object according to the position of the measured object feature.

[0076] 当针对胎儿进行超声检测吋，得到的是胎儿的三维体数据，可根据胎儿的图像特征从所述体数据集中识别出多个子集，胎儿的图像特征可以是胎儿脸部特征、胎儿肢体结构特征、胎儿脐带特征等，根据胎儿脸部特征识别出的子集为胎儿脸部子集，用于生成胎儿脸部图像。胎儿脸部特征包括：在超声三维体数据中胎儿脸部上一个或多个组织结构的解剖学结构对应的图像特性，所述 1个或多个组织结构从胎儿眼睛、胎儿鼻子、胎儿额头、胎儿下巴、胎儿脸颊、胎儿耳朵、胎儿脸轮廓和胎儿嘴等中选择。 [0076] When the ultrasound is detected for the fetus, the three-dimensional volume data of the fetus is obtained, and a plurality of subsets can be identified from the volume data set according to the image characteristics of the fetus, and the image characteristics of the fetus may be fetal facial features, fetuses The limb structure features, the fetal umbilical cord features, and the like, the subset identified according to the fetal facial features is a subset of the fetal face, and is used to generate a fetal facial image. The fetal facial features include: image characteristics corresponding to the anatomical structure of one or more tissue structures on the fetal face in the ultrasound three-dimensional volume data, the one or more tissue structures from the fetal eye, the fetal nose, the fetal forehead, Choose from fetal chin, fetal cheeks, fetal ears, fetal face contours and fetal mouth.

[0077] 步骤 12，对多个子集的全部或部分进行渲染。本实施例中，以对多个子集进行区别性渲染为例进行说明。预先建立多套不同的显示配置，显示配置的内容包含但不局限于： [0077] Step 12: Render all or part of the plurality of subsets. In this embodiment, to perform on multiple subsets Distinctive rendering is illustrated as an example. Multiple sets of different display configurations are pre-established, and the contents of the display configuration include but are not limited to:

[0078] 1. [0078] 1.

渲染模式的选择，如表面模式、 HDLive模式、最小值模式、最大值模式、 X-Ray 模式、反转模式等等； Selection of rendering modes, such as surface mode, HDLive mode, minimum mode, maximum mode, X-Ray mode, reverse mode, etc.

[0079] 2.渲染参数的选择，如伪彩、色调、亮度、阈值、不透明度、对比度、深度渲染参数以及 VR图的后处理参数等等； [0079] 2. Selection of rendering parameters, such as pseudo color, hue, brightness, threshold, opacity, contrast, depth rendering parameters, and post processing parameters of the VR map;

[0080] 3.光源的选择，如光源模式（点光源、平行光源等）、光源位置等； [0080] 3. Selection of the light source, such as a light source mode (point light source, parallel light source, etc.), light source position, etc.;

[0081] 4.体数据前处理 /后处理的选择，如增益档位、平滑档位、去噪档位等等。 [0081] 4. Selection of volume data pre-processing/post-processing, such as gain gear position, smooth gear position, denoising gear position, and the like.

[0082] 每套显示配置中，至少有一项内容不同于其他的显示配置，因此构成不同的多套显示配置，采用多套显示配置分别对多个子集进行渲染，每套显示配置可渲染出一种渲染结果。在渲染吋，可以是每个子集使用不同于其它子集的一套显示配置进行渲染，得到一种不同于其它子集的渲染结果。或将多个子集分成至少两组，每组使用不同于其它组的一套显示配置进行渲染，每组有一种不同于其它组的渲染结果。 [0082] In each display configuration, at least one content is different from other display configurations, so that different sets of display configurations are configured, and multiple sets of display configurations are used to respectively render multiple subsets, and each set of display configurations can render one. Kind of rendering results. In rendering, each subset can be rendered using a different set of display configurations than the other subsets, resulting in a different rendering result than the other subsets. Or divide multiple subsets into at least two groups, each group is rendered using a set of display configurations different from the other groups, each group having a different rendering result than the other groups.

[0083] 在对多个子集的全部或部分进行渲染后获得多个子图像，可对该多个子图像全部或部分进行融合显示，得到整体的三维图像，使得在该三维图像中，各子图像呈现半透明显示效果，所谓半透明是指既能对本身子集的体数据进行显示，但又不遮挡其它子集的体数据的显示，从而可同吋显示出多个子图像。 [0083] After rendering all or part of the plurality of subsets to obtain a plurality of sub-images, all or part of the plurality of sub-images may be fused and displayed to obtain an overall three-dimensional image, so that each sub-image is presented in the three-dimensional image. Translucent display effect, so-called translucent means that the volume data of its own subset can be displayed, but the display of the volume data of other subsets is not blocked, so that multiple sub-images can be displayed simultaneously.

[0084] 可采用各种方式对多个子图像全部或部分进行融合显示，在一种具体实施例中，采用融合系数的方式实现融合显示，如步骤 13-14所示。 [0084] The fused display may be performed on all or part of the plurality of sub-images in various manners. In a specific embodiment, the fusion display is implemented by using a fusion coefficient, as shown in steps 13-14.

[0085] 步骤 13，获取各子集的融合系数。在具体的实施例中，融合系数可以是***预设好的融合系数，也可以是用户设定好的融合系数，例如，为每个对象设定一个融合系数，规定位于前方的对象的融合系数为 1或 0.6，位于后方的对象的融合系数为 0或 0.4，用户可根据需要或临床含义设定对象的前后相对位置关系。在有的实施例中，还可以采用自适应的融合系数，自适应融合系数可根据对象的位置不同而不同，可以根据对象的厚薄而变化，也可以根据对象的密度而变化。各子集的自适应融合系数可按照各种融合规则计算出来。融合系数是一个 0至 1 之间的值，但各子集的融合系数的总和可以等于 1，也可以大于或小于 1。 [0085] Step 13: Acquire a fusion coefficient of each subset. In a specific embodiment, the fusion coefficient may be a fusion coefficient preset by the system, or may be a fusion coefficient set by the user. For example, a fusion coefficient is set for each object, and the fusion coefficient of the object located in front is specified. For 1 or 0.6, the fusion coefficient of the object located at the back is 0 or 0.4, and the user can set the relative positional relationship of the object according to needs or clinical meaning. In some embodiments, adaptive fusion coefficients may also be used. The adaptive fusion coefficients may vary according to the position of the object, may vary according to the thickness of the object, or may vary according to the density of the object. The adaptive fusion coefficients for each subset can be calculated according to various fusion rules. The fusion coefficient is a 0 to 1 The value between, but the sum of the fusion coefficients of each subset can be equal to 1, or can be greater or less than 1.

[0086] 步骤 14，将多个子集的渲染结果乘以各自的融合系数后进行叠加显示。分别将各子集在步骤 12中得到的渲染结果乘以各自融合系数，然后将乘以融合系数的结果叠加在一起，相当于将各子集的渲染结果按照各自的融合系数进行了削弱，例如，子集的融合系数是 0.4，相当于将该子集的渲染效果削弱了 60%。通常情况下，各子集的渲染参数中不透明参数的值为 1，在视觉效果上是不透明。渲染结果削弱后使其显示效果变得更加轻薄，在视觉效果上变得更透明。 [0086] Step 14. Multiply the rendering results of the plurality of subsets by the respective fusion coefficients and perform overlay display. Multiplying the rendering results obtained by the subsets in step 12 by the respective fusion coefficients, and then superimposing the results of multiplying the fusion coefficients, is equivalent to attenuating the rendering results of the subsets according to their respective fusion coefficients, for example The fusion coefficient of the subset is 0.4, which is equivalent to a 60% reduction in the rendering effect of the subset. Typically, the value of the opacity parameter in the render parameters for each subset is 1, which is visually opaque. When the rendering result is weakened, the display effect becomes lighter and thinner, and the visual effect becomes more transparent.

[0087] 当多个对象在某个视角上处于前后重叠吋，即从某个视角看，前后的对象的全部或部分或遮挡后面对象的全部或部分，不管是只采用一种显示配置对多个对象进行渲染，还是采用不同的显示配置对多个对象进行渲染，如果不降低渲染结果的不透明度，则要么是位于前面的对象会遮挡后面的对象，导致后面的对象显示不出来，要么是只将医生选择的感兴趣对象进行渲染显示，而其他对象中与感兴趣对象重叠的部分则不再被渲染显示，而医生可根据需要选择其中的一个或多个对象为感兴趣对象。如图 3所示，图中胎盘部分 313a位于胎儿脸部 313 b前面，胎盘部分 313a和胎儿脸部 313b采用相同的显示配置进行渲染，并且渲染参数的不透明度都是 1，因此渲染结果中，胎儿脸部 313b的部分区域被胎盘部分 313a遮挡，这种情况下，医生看不到胎儿脸部 313b的完整渲染图像。 [0087] When a plurality of objects are overlapped in a certain perspective, that is, from a certain perspective, all or part of the objects before and after or occlusion of all or part of the objects behind, whether or not only one display configuration is used. Objects are rendered, or multiple objects are rendered with different display configurations. If the opacity of the rendering result is not reduced, either the object in front will obscure the object behind it, causing the subsequent objects to not be displayed, or Only the object of interest selected by the doctor is rendered and displayed, and the parts of other objects that overlap with the object of interest are no longer rendered, and the doctor can select one or more of the objects as objects of interest as needed. As shown in FIG. 3, the placenta portion 313a is located in front of the fetal face 313b, the placenta portion 313a and the fetal face 313b are rendered in the same display configuration, and the opacity of the rendering parameters is 1, so in the rendering result, A partial area of the fetal face 313b is blocked by the placental portion 313a, in which case the doctor does not see the full rendered image of the fetal face 313b.

[0088] 在采用本实施例的渲染融合方案吋，通过将渲染结果乘以融合系数后按照一定的比例叠加显示，使得不同区域根据各自的比例同吋显示在屏幕上，获得部分透明（也称为半透明）的效果，可使得重叠部分中各对象呈现出半透明状态，即使空间相对位置上处于后面的对象也不会被前面的对象完全遮盖，因此用户 [0088] In the rendering fusion scheme of the embodiment, by multiplying the rendering result by the fusion coefficient and superimposing the display according to a certain ratio, different regions are displayed on the screen according to their respective proportions, and partial transparency is obtained (also called The effect of being translucent can make each object in the overlapping part appear translucent, even if the object in the opposite position of the space is not completely covered by the previous object, so the user

(例如医生）可同吋直观地看到多个对象的表现。如图 4所示，胎盘部分 313a和胎儿脸部 313b都呈现出半透明渲染效果，虽然胎盘部分 313a位于胎儿脸部 313b的前面，也不会完全遮盖后面的胎儿脸部图像，医生可同吋直观地看到重叠部分的胎盘部分 313a和胎儿脸部 313b的细节表现。 (for example, a doctor) can visually see the performance of multiple objects. As shown in FIG. 4, both the placenta portion 313a and the fetal face 313b exhibit a translucent rendering effect. Although the placenta portion 313a is located in front of the fetal face 313b, it does not completely cover the posterior fetal face image, and the doctor can simultaneously The detailed representation of the placental portion 313a and the fetal face 313b of the overlapping portion is visually seen.

[0089] 当融合系数采用各子集的自适应融合系数吋，在视觉效果上不同部分显示的透明度不同，可使医生直观的感受到对象的性质，例如对象的厚度、对象的密度等等。在本实施例的一种实例中，可采用光线跟踪法来计算各子集的自适应融合系数，光线跟踪法的原理是沿着到达视点的光线的反方向进行跟踪，相当于跟踪从眼睛发出的光线，当光线与场景中的物体或者媒介相交的吋候计算光线的反射、折射以及吸收。本实施例中，采用光线跟踪法计算各子集的自适应融合系数的流程如图 5所示，包括以下步骤： [0089] When the fusion coefficient adopts the adaptive fusion coefficient 各 of each subset, the transparency of different parts displayed in the visual effect is different, so that the doctor can intuitively feel the nature of the object, such as the thickness of the object, the density of the object, and the like. In an example of the embodiment, the ray tracing method can be used to calculate the adaptive fusion of each subset. Coincidence coefficient, the principle of ray tracing is to follow the opposite direction of the light reaching the viewpoint, which is equivalent to tracking the light emitted from the eye, and calculating the reflection and refraction of the light when the light intersects with the object or medium in the scene. absorb. In this embodiment, the process of calculating the adaptive fusion coefficient of each subset by using the ray tracing method is as shown in FIG. 5, and includes the following steps:

[0090] 步骤 131，采用光线跟踪法计算各子集在各跟踪光线上的体素值。如图 6所示，从视点 210发出很多束跟踪光线，跟踪光线为模拟出的光线，模拟这些跟踪光线分别穿过要显示的各对象的三维图像，每束跟踪光线按照一个视角入射到三维图像中，有的跟踪光线穿过多个对象，有的跟踪光线只穿过一个对象。下面以图 4中的跟踪光线 220穿过第一对象 230和第二对象 240为例进行说明。临床上，例如第二对象 240是胎儿脸部，第一对象 230可以是胎盘部分，胎盘部分遮挡在胎儿脸部前面。首先识别出跟踪光线 220穿过第一对象 230和第二对象 240吋途经的体素，获取这些途经体素的体素值，该体素值根据多帧超声回波数据得到，体素值反映该位置对超声波的反射强度。对于液体（例如血液），其对超声波的反射较弱，超声波回波信号较弱，得到的体素值较小；对于密度较大的固体 (例如骨头或介入物），其与其他软组织的边界对超声波的反射较强，超声波回波信号较强，得到的体素值较大。 [0090] Step 131: Calculate the voxel value of each subset on each tracking ray by using a ray tracing method. As shown in FIG. 6, a plurality of beam tracking rays are emitted from the viewpoint 210, and the tracking rays are simulated rays, and the tracking rays are simulated to pass through the three-dimensional images of the objects to be displayed, and each of the tracking rays is incident on the three-dimensional image according to one viewing angle. In some, some tracking rays pass through multiple objects, and some tracking rays pass through only one object. The following description will be made by taking the tracking ray 220 in FIG. 4 through the first object 230 and the second object 240 as an example. Clinically, for example, the second subject 240 is a fetal face, the first subject 230 can be a placental portion, and the placenta portion is obscured in front of the fetal face. First, the voxels passing through the first object 230 and the second object 240 are identified, and voxel values of the path voxels are obtained, and the voxel values are obtained according to the multi-frame ultrasonic echo data, and the voxel values are reflected. The intensity of the reflection of this position on the ultrasonic waves. For liquids (such as blood), the reflection of the ultrasound is weak, the ultrasonic echo signal is weak, and the obtained voxel value is small; for dense solids (such as bones or interventions), its boundary with other soft tissues The reflection of the ultrasonic wave is strong, the ultrasonic echo signal is strong, and the obtained voxel value is large.

[0091] 然后确定途经体素所归属的子集，计算归属第一对象 230子集的途经体素的体素值综合，即第一对象 230子集在该跟踪光线 220上的体素值，计算归属第二对象 240子集的途经体素的体素值综合，即第二对象 240子集在该跟踪光线 220上的体素值。 [0091] then determining the subset to which the voxel belongs, and calculating the voxel value integration of the path voxels belonging to the subset of the first object 230, that is, the voxel value of the subset of the first object 230 on the tracking ray 220, The voxel value integration of the path voxels belonging to the subset of the second object 240 is calculated, that is, the voxel value of the second object 240 subset on the tracking ray 220.

[0092] 步骤 132，获取各子集在跟踪光线上的空间分布。即根据途经体素所归属的子集，得到各子集在跟踪光线上所分布的区域，也就是各子集在跟踪光线上厚度分布。 [0092] Step 132: Acquire spatial distribution of each subset on the tracking ray. That is, according to the subset to which the voxel belongs, the regions in which the subsets are distributed on the tracking ray are obtained, that is, the thickness distribution of each subset on the tracking ray.

[0093] 步骤 133，识别各子集在跟踪光线入射方向上所处的空间位置。如图 6所示，跟踪光线 220由视点 210发出，先经第一对象 230，再经第二对象 240，因此第一对象 230子集相对于第二对象 240子集为空间位置靠前的子集，第二对象 240子集为空间位置靠后的子集。 [0093] Step 133: Identify a spatial position where each subset is in the direction in which the light is incident. As shown in FIG. 6, the tracking ray 220 is emitted by the viewpoint 210, first through the first object 230, and then through the second object 240, so the subset of the first object 230 is a spatially advanced child relative to the second object 240 subset. Set, the second object 240 subset is a subset of the spatial position.

[0094] 步骤 134，确定各子集在各跟踪光线上的融合系数，融合系数为一 0到 1之间的值。各子集在跟踪光线上的融合系数可根据各子集在跟踪光线上的体素值、空间分布和空间位置中的至少一者确定，可以根据以下方式中的至少一个规则确定融合系数： [0094] Step 134: Determine a fusion coefficient of each subset on each tracking ray, and the fusion coefficient is between 0 and 1. Value. The fusion coefficients of the subsets on the tracking ray may be determined according to at least one of voxel values, spatial distributions, and spatial locations of the subsets on the tracking ray, and the fusion coefficients may be determined according to at least one of the following manners:

[0095] 在该跟踪光线入射方向上，空间位置靠前的子集相对于空间位置靠后的子集具有较大的融合系数，这意味着前面的对象相对于后面的对象更加的不透明度，使得用户根据对象的不透明度即可判断对象的空间相对位置。 [0095] In the incident direction of the tracking ray, the subset of the front of the spatial position has a larger fusion coefficient with respect to the subset of the space position, which means that the front object is more opaque with respect to the latter object. The user can determine the relative position of the object according to the opacity of the object.

[0096] 在该跟踪光线上，体素值较大的子集相对于体素值较小的子集具有较大的融合系数，这意味着密度较大的固体（例如骨头）相对于肌肉和液体而言更加不透明，使得用户根据对象的不透明度即可判断对象是何种组织。 [0096] On the tracking ray, a subset with a larger voxel value has a larger fusion coefficient than a subset with a smaller voxel value, which means that a denser solid (eg, bone) is relative to the muscle and The liquid is more opaque, allowing the user to determine which tissue the object is based on the opacity of the object.

[0097] 在该跟踪光线上，体素分布范围较大的子集相对于体素分布范围较小的子集具有较大的融合系数，这意味着厚度较大的部分更加不透明，使得用户根据对象的不透明度即可判断对象在该位置处的厚度。 [0097] On the tracking ray, the subset having a larger voxel distribution range has a larger fusion coefficient than the subset having a smaller voxel distribution range, which means that the thicker portion is more opaque, so that the user The opacity of the object determines the thickness of the object at that location.

[0098] 根据***预定的规则或用户设置的规则，采用本步骤中的方法可确定各子集在跟踪光线 220上的融合系数，由于该融合系数跟随子集的厚度、密度和 /或空间位置而变化，因此属于自适应的融合系数，依此类推可得到各视角的跟踪光线上的各子集的融合系数。在步骤 14中，将跟踪光线上各子集的渲染结果乘以各子集在该跟踪光线上的融合系数后进行叠加显示。 [0098] According to a predetermined rule of the system or a rule set by the user, the fusion coefficient of each subset on the tracking ray 220 can be determined by the method in this step, since the fusion coefficient follows the thickness, density and/or spatial position of the subset. The change, therefore, is an adaptive fusion coefficient, and so on, the fusion coefficients of the subsets on the tracking ray of each view can be obtained. In step 14, the rendering result of each subset on the tracking ray is multiplied by the fusion coefficient of each subset on the tracking ray and then superimposed and displayed.

[0099] 上述步骤中，本领域技术人员应当理解，步骤 13也可以和步骤 12调换吋序，即先获取各子集的融合系数，再对各子集进行区别性渲染。步骤 14可在各子集渲染之后融合，也可以在各子集渲染过程中融合，即边渲染边融合。 [0099] In the above steps, those skilled in the art should understand that step 13 can also be exchanged with step 12, that is, the fusion coefficients of each subset are obtained first, and then the subsets are separately rendered. Step 14 can be merged after rendering of each subset, or it can be fused during the rendering of each subset, that is, edge rendering.

[0100] 在有些情况下，在步骤 11中，当从体数据集中根据对象的不同识别各个子集吋 [0100] In some cases, in step 11, when the slave data set identifies each subset according to the object 吋

，有吋会将一部分体数据既识别到第一子集，同吋又将该部分体数据识别到第二子集中，本文将被识别到至少两个子集中的体数据称为共有体数据，这种情况下，对于共有体数据，按照其归属子集所使用的任一种显示配置进行渲染，或采用一种与各相关子集或分组均不相同的显示配置进行渲染，同样也会计算这部分共用体数据的融合系数，最后将其渲染结果乘以其融合系数后与其他对象进行叠加显示。 The 吋 will identify a part of the volume data to the first subset, and identify the part of the volume data to the second subset. In this paper, the volume data identified in at least two subsets is called the consensus data. In this case, for the consensus data, rendering is performed according to any display configuration used by the belonging subset, or by using a display configuration that is different from each related subset or group, and this is also calculated. The fusion coefficient of the partial union data is finally superimposed with other objects by multiplying the rendering result by its fusion coefficient.

[0101] [0102] 实施例二： [0101] Embodiment 2:

[0103] 在实施例一的基础上，处理器还用于将相邻子集的边界部分的体数据由原先归属的子集调整到相邻子集，并使用相邻子集的显示配置对被调整体数据进行渲染，以对显示的对象或区域进行调整。调整的方式包括但不局限于： [0103] On the basis of the first embodiment, the processor is further configured to adjust the volume data of the boundary part of the adjacent subset from the previously belonged subset to the adjacent subset, and use the display configuration pair of the adjacent subset. The adjusted volume data is rendered to adjust the displayed object or area. Adjustments include but are not limited to:

[0104] 1.选择不同的划分策略 /算法对区域或对象进行重新划分，如根据不同的分割目标或临床意义，使用不同的模型对区域或对象进行重新的划分； [0104] 1. Selecting different partitioning strategies/algorithms to re-divide regions or objects, such as re-dividing regions or objects using different models according to different segmentation goals or clinical significance;

[0105] 2.使用裁剪的操作或应用额外的算法，将现有的划分区域或对象分为多个更小的感兴趣区域；或者去除现有划分区域或对象的一部分，缩小其感兴趣区域的范围； [0105] 2. Using the cropping operation or applying an additional algorithm, dividing the existing divided area or object into a plurality of smaller areas of interest; or removing the existing divided area or a part of the object, and narrowing the area of interest thereof Scope

[0106] 3.合并现有的划分区域；或者扩充感兴趣区域的范围，使部分非感兴趣区域加入到感兴趣区域中； [0106] 3. Merging the existing divided regions; or expanding the range of the regions of interest to add some non-interesting regions to the region of interest;

[0107] 4.对划分区域之间的分割面作整体的调整，如对分割面作整体的平移与旋转、调整分割面上控制点的位置或分割面方程的参数以改变分割面形状与位置，或者更换分割面的数学模型等等； [0107] 4.

[0108] 5.对划分区域或对象之间的分割面作局部的调整，如使用画笔、橡皮擦等工具或挪动分割面上的部分控制点来局部地增加 /减少某个划分区域的范围；与此同吋，其他划分区域或对象也可能会相应地减少 /增加其范围。 [0108] 5. Locally adjusting the divided surface between the divided regions or objects, such as using a brush, an eraser or the like or moving some of the control points on the split surface to locally increase/decrease the range of a certain divided region; Similarly, other partitions or objects may also reduce/increase their range accordingly.

[0109] 在有些情况下，在步骤 11中，当从体数据集中根据对象的不同识别各个子集吋，有吋会对一部分体数据产生误识别，因此可能会出现医生根据临床经验对一部分体数据所归属的子集进行调整，这种情况下就需要用到画笔或橡皮擦等微调工具调整该部分体数据。用户的调整操作可通过控制终端输入指令，以达到调整显示器上输出图像的目的。如图 7所示为一种控制终端的示意图，图中人机交互装置 300包括显示器 310、控制面板 320和触控屏 330，控制面板 320和触控屏 330构成控制终端，在有的实施例中，也可以没有触控屏。 [0109] In some cases, in step 11, when each subset is identified from the volume dataset according to the object, a certain part of the volume data may be misidentified, so that a doctor may have a part of the body based on clinical experience. The subset to which the data belongs is adjusted. In this case, a fine adjustment tool such as a brush or an eraser is required to adjust the partial volume data. The user's adjustment operation can be used to adjust the output image on the display by inputting commands through the control terminal. FIG. 7 is a schematic diagram of a control terminal. The human-machine interaction device 300 includes a display 310, a control panel 320, and a touch screen 330. The control panel 320 and the touch screen 330 constitute a control terminal. In some embodiments, There is also no touch screen.

[0112] 控制面板 320上可设置有各种操作键，例如通过按压操作的键盘 321、旋钮 322- 326、增益键 327、滚轮（或轨迹球） 328。对于显示有多个渲染对象的三维超声图像，每个渲染对象可对应一个操作键，如图 8所示，三维超声图像 313中显示有多个渲染对象，例如胎盘部分 313a和胎儿脸部 313b，胎盘部分 313a对应旋钮 32 2，胎儿脸部 313b对应旋钮 323，即当用户操作旋钮 322吋，认为是对胎盘部分 31 3a的选定和操作，当用户操作旋钮 323吋，认为是对胎儿脸部 313b的选定和操作，旋钮 324可以是一个多档幵关，用于选择操作类型，操作类型包括裁剪、合并、分割面调整、画笔、橡皮擦等，例如当旋钮 324选择画笔吋，通过操作滚轮 32 8可在显示区域 311中的图像上进行涂画操作，当旋钮 324选择橡皮擦吋，通过操作滚轮 328可在显示区域 311中的图像上进行擦拭操作。下面以擦拭操作为例进行说明其操作流程，如图 9所示包括以下步骤： [0112] The operation panel 320 may be provided with various operation keys, such as a keyboard 321 and a knob 322- 326, gain button 327, scroll wheel (or trackball) 328. For a three-dimensional ultrasound image displaying a plurality of rendering objects, each rendering object may correspond to one operation key. As shown in FIG. 8, a plurality of rendering objects, such as a placenta portion 313a and a fetal face 313b, are displayed in the three-dimensional ultrasound image 313. The placenta portion 313a corresponds to the knob 32 2, and the fetal face 313b corresponds to the knob 323, that is, when the user operates the knob 322, it is considered to be the selection and operation of the placenta portion 31 3a. When the user operates the knob 323, it is considered to be the face of the fetus. For the selection and operation of 313b, the knob 324 can be a multi-step switch for selecting the operation type, and the operation type includes cropping, merging, splitting surface adjustment, brush, eraser, etc., for example, when the knob 324 selects the brush 吋, by operation The roller 32 8 can perform a painting operation on the image in the display area 311, and when the knob 324 selects the eraser, the wiping operation can be performed on the image in the display area 311 by operating the roller 328. The operation flow is described below by taking a wiping operation as an example. As shown in FIG. 9, the following steps are included:

[0113] 步骤 20，检测用户所选择的调整操作。用户通过控制面板上旋钮 324选择擦拭操作。 [0113] Step 20: Detect an adjustment operation selected by the user. The user selects the wiping operation via knob 324 on the control panel.

[0114] 步骤 21，检测用户所选择的子集和在叠加显示图像上所选择的区域。用户通过滚轮 328控制显示区域的鼠标移动，可控制鼠标移动到胎盘部分 313a和胎儿脸部 3 13b重叠的区域，当检测到用户对旋钮 322旋转吋，认为用户选定的数据是归属到胎盘部分 313a子集的体数据，当检测到用户对旋钮 323旋转吋，认为用户选定的数据是归属到胎儿脸部 313b子集的体数据。 [0114] Step 21: Detect a subset selected by the user and an area selected on the superimposed display image. The user controls the mouse movement of the display area through the scroll wheel 328, and can control the mouse to move to the area where the placenta portion 313a and the fetal face 3 13b overlap. When the user detects that the knob 322 is rotated, the user selects that the selected data belongs to the placenta portion. The volume data of the subset 313a, when it is detected that the user rotates the knob 323, considers that the data selected by the user is volume data belonging to a subset of the fetal face 313b.

[0115] 步骤 22，根据用户选择的子集和区域确定被调整体数据。用户选择的区域可通过圆圈 313c确定，圆圈 313c代表以该圆半径为半径的圆球，即圆球内的三维体数据是被调整体数据，用户可通过旋转旋钮 322、 323改变圆圈 313c的半径，即改变圆球的半径，从而改变被调整体数据的范围。 [0115] Step 22: Determine the adjusted volume data according to the subset and the region selected by the user. The area selected by the user can be determined by a circle 313c, and the circle 313c represents a sphere having a radius of the circle radius, that is, the three-dimensional volume data in the sphere is the adjusted volume data, and the user can change the radius of the circle 313c by rotating the knobs 322 and 323. , that is, changing the radius of the sphere, thereby changing the range of the adjusted volume data.

[0116] 步骤 23，响应于用户输入的模仿擦拭操作，将被调整体数据由原先归属的子集调整到相邻子集。当圆圈 313c的半径确定后，用户对滚轮 328进行操作，基于用户对滚轮 328的操作，显示屏上的图标可改变为一橡皮擦图形，并随着用户对滚轮 328的操作往复擦拭，将被调整体数据由原先归属的子集调整到相邻子集。当用户需要继续调整吋，可继续对滚轮 328进行操作， ***再次根据圆圈 313c确定被调整体数据，并将被调整体数据由原先归属的子集调整到相邻子集。如果以胎儿脸部为参照对象，则当用户选择橡皮擦将体数据由胎儿脸部 313b子集调整到胎盘部分 313a子集吋，称为"擦除"，将体数据由胎盘部分 313a子集调整到胎儿脸部 313b子集吋，称为"反擦除"。 [0116] Step 23: Adjust the adjusted volume data from the originally assigned subset to the adjacent subset in response to the simulated wiping operation input by the user. When the radius of the circle 313c is determined, the user operates the scroll wheel 328. Based on the user's operation of the scroll wheel 328, the icon on the display screen can be changed to an eraser pattern, and as the user reciprocates the roller 328, it will be The adjustment volume data is adjusted from the previously assigned subset to the adjacent subset. When the user needs to continue adjusting, the scroll wheel 328 can continue to operate, the system again determines the adjusted volume data according to the circle 313c, and adjusts the adjusted volume data from the previously assigned subset to the adjacent subset. If the fetal face is used as a reference object, when the user selects the eraser, the volume data is adjusted from the subset of the fetal face 313b. A subset of the placental portion 313a, referred to as "erasing", is adjusted from the subset of the placental portion 313a to a subset of the fetal face 313b, referred to as "anti-erasing."

[0117] 步骤 24，使用相邻子集的显示配置对被调整体数据进行渲染，使被调整体数据与新归属的子集具有相同的渲染效果。 [0117] Step 24: Render the adjusted volume data by using the display configuration of the adjacent subset, so that the adjusted volume data has the same rendering effect as the newly assigned subset.

[0118] 本实施例在进行体数据调整前，先将多个不同的对象进行区别性渲染并融合显示，这使得用户可査看到被调整的体数据的现状，可辅助用户判断所确定的被调整体数据是否存在，以及调整操作是否正确。例如，对于胎儿脸部图像，医生根据临床经验判断胎儿鼻子部分的图像有缺损，这种缺损有可能是超声设备在识别各个子集吋产生的误识别，也有可能是该胎儿确实存在鼻子缺损的缺陷，如果能够同吋看到与鼻子重叠的其他对象（例如胎盘）的渲染显示，则可根据经验判断是否存在体数据的误识别，例如将本应归属到胎儿脸部子集的体数据误识别到了胎盘子集，这种情况下，医生可将这部分体数据由胎盘子集调整到胎儿脸部子集，使胎儿的鼻子部分的图像变得完整，同理，如果不存在体数据的误识别，例如胎盘图像中也没有这部分体数据，则医生可判断胎儿确实存在鼻子缺损的缺陷。因此，本实施例可提高后期诊断的准确性。 [0118] Before performing volume data adjustment, the present invention performs differential rendering and fusion display on a plurality of different objects, so that the user can view the current status of the adjusted volume data, and can assist the user in determining the determined status. Whether the adjusted volume data exists and whether the adjustment operation is correct. For example, for fetal facial images, the doctor judges that the image of the fetal nose is defective according to clinical experience. This defect may be caused by the misidentification of the ultrasound device in identifying each subset, or it may be that the fetus does have a nose defect. Defects, if you can see the rendered display of other objects (such as the placenta) that overlap with the nose, you can judge whether there is misidentification of the volume data based on experience, such as the body data that should belong to the fetal face subset. The set of fetal plates is identified. In this case, the doctor can adjust this part of the body data from the set of fetal plates to the subset of the fetal face, so that the image of the nose part of the fetus becomes complete. Similarly, if there is no volume data. Misidentification, such as the absence of this part of the body data in the placenta image, the doctor can determine that the fetus does have a defect in the nose defect. Therefore, this embodiment can improve the accuracy of the later diagnosis.

[0119] 在另一种实施例中， "擦除 "和"反擦除"的效果还可通过另一种方案实现，例如，当以胎儿脸部为参照对象吋，胎儿脸部对应旋钮 323，当用户操作旋钮 323吋，认为是对胎儿脸部 313b的选定和操作，对胎儿脸部进行"擦除"的操作包括以下步骤： [0119] In another embodiment, the effects of "erasing" and "anti-erasing" may also be achieved by another scheme, for example, when the fetal face is referred to as a reference object, the fetal face corresponding knob 323 When the user operates the knob 323, which is considered to be the selection and operation of the fetal face 313b, the operation of "erasing" the fetal face includes the following steps:

[0120] 1.1接收用户在三维图像上输入的第二指令。例如用户可通过操作旋钮 324，将旋钮 324选择到 "擦除 "档，用户的该操作认为是用户输入的第二指令。 [0120] 1.1 receiving a second instruction entered by the user on the three-dimensional image. For example, the user can select the knob 324 to "erase" by operating the knob 324, and the user's operation is considered to be the second command input by the user.

[0121] 1.2根据第二指令，识别用户的输入对应在三维图像上的第一位置以及第一位置所处的子集。用户通过移动光标，将光标移动到需要"擦除"的位置，当用户将旋钮 324选择到"擦除"档吋，可将光标的图标改变为对应的图标，例如将光标的图标变换为圆形图标，用户通过旋转旋钮 323，可改变圆形图标的大小，从而确定用户选择的第一位置所覆盖区域的大小。因为用户是对旋钮 323进行操作，因此可认为用户是对胎儿脸部进行"擦除"操作，第一位置所处的子集是胎儿脸部子集。 [0122] 1.3根据第一位置，确定在第一位置所处的子集中第一位置所包括的体数据。对于圆形图标的光标而言，第一位置所包括的体数据是指位于以圆形图标的半径为半径的圆球内的胎儿脸部的体数据。 [0121] 1.2 According to the second instruction, the input of the user is identified to correspond to the first location on the three-dimensional image and the subset in which the first location is located. The user moves the cursor to the position where "erasing" is required by moving the cursor. When the user selects the knob 324 to "erase" the file, the icon of the cursor can be changed to the corresponding icon, for example, the icon of the cursor is converted into a circle. The icon, the user can change the size of the circular icon by rotating the knob 323, thereby determining the size of the area covered by the first position selected by the user. Since the user operates the knob 323, the user is considered to be an "erase" operation on the face of the fetus, the subset of which is the subset of the fetal face. [0122] 1.3 determining, according to the first location, volume data included in the first location in the subset in which the first location is located. For the cursor of the circular icon, the volume data included in the first position refers to the volume data of the fetal face located in the sphere having the radius of the radius of the circular icon.

[0123] 1.4降低第一位置所处的子集所对应的子图像的融合系数，本实施例中，即降低胎儿脸部子图像的融合系数，使得胎儿脸部图像看起来更加透明，从而实现胎儿脸部图像被"擦除"的效果。 [0123] 1.4 reducing the fusion coefficient of the sub-image corresponding to the subset in which the first location is located, in this embodiment, reducing the fusion coefficient of the fetal face sub-image, so that the fetal facial image looks more transparent, thereby realizing The fetal face image is "erased".

[0124] 在另一实施例中，也可以降低第一位置所包括的体数据所对应的子图像的融合系数，即降低胎儿脸部图像中第一位置所覆盖区域的图像的融合系数，使得第一位置所覆盖区域的图像看起来更加透明，从而实现胎儿脸部图像上的局部被" 擦除"的效果。 [0124] In another embodiment, the fusion coefficient of the sub-image corresponding to the volume data included in the first position may be reduced, that is, the fusion coefficient of the image of the area covered by the first position in the fetal facial image is reduced, so that The image of the area covered by the first location appears to be more transparent, thereby achieving a partial "erasing" effect on the fetal facial image.

[0125] 当对胎儿脸部进行"反擦除 "操作吋，包括以下流程： [0125] When the "anti-erase" operation is performed on the fetal face, the following processes are included:

[0126] 2.1接收用户在三维图像上输入的第三指令。例如用户可通过操作旋钮 324，将旋钮 324选择到 "反擦除"档，用户的该操作认为是用户输入第三指令。 [0126] 2.1 Receive a third instruction entered by the user on the three-dimensional image. For example, the user can select the knob 324 to "anti-erase" by operating the knob 324, and the user's operation is considered to be the user inputting the third command.

[0127] 2.2根据第三指令，识别用户的输入对应在三维图像上的第二位置以及第二位置所处的子集。同样，用户通过移动光标，将光标移动到需要"反擦除 "的位置，用户通过旋转旋钮 323，可改变圆形图标的大小，从而确定用户选择的第二位置所覆盖区域的大小。因为用户是对旋钮 323进行操作，因此可认为用户是对胎儿脸部进行"反擦除"操作，第二位置所处的子集是胎儿脸部子集。 [0127] 2.2 According to the third instruction, the input of the user is identified to correspond to the second location on the three-dimensional image and the subset at which the second location is located. Similarly, the user moves the cursor to the position where "anti-erase" is required by moving the cursor. By rotating the knob 323, the user can change the size of the circular icon to determine the size of the area covered by the second position selected by the user. Since the user operates the knob 323, the user is considered to be "anti-erasing" the face of the fetus, and the subset at which the second position is located is a subset of the fetal face.

[0128] 2.3根据第二位置，确定在第二位置所处的子集中第二位置所包括的体数据；对于圆形图标的光标而言，第二位置所包括的体数据是指位于以圆形图标的半径为半径的圆球内的胎儿脸部的体数据。 [0128] 2.3 determining, according to the second position, volume data included in the second position in the subset in which the second position is located; for the cursor of the circular icon, the volume data included in the second position is located in a circle The radius of the icon is the volume data of the fetal face within the radius of the sphere.

[0129] 2.4提高第二位置所处的子集所对应的子图像的融合系数，或提高第二位置所包括的体数据所对应的子图像的融合系数。即提高胎儿脸部子图像的融合系数，使得胎儿脸部图像看起来更加不透明，或提高胎儿脸部图像中第二位置所覆盖区域的图像的融合系数，使得第二位置所覆盖区域的图像看起来更加不透明，从而实现胎儿脸部图像被"反擦除 "的效果。 [0129] 2.4 increasing the fusion coefficient of the sub-image corresponding to the subset in which the second position is located, or increasing the fusion coefficient of the sub-image corresponding to the volume data included in the second position. That is, the fusion coefficient of the fetal face image is improved, so that the fetal face image looks more opaque, or the fusion coefficient of the image of the area covered by the second position in the fetal facial image is improved, so that the image of the area covered by the second position is seen. It is more opaque, so that the image of the fetal face is "anti-erased".

[0130] [0130]

[0131] 实施例三： [0132] 当三维图像旋转到某个角度吋，或三维图像从某个视角去观察吋，胎儿脸部有吋会被其它结构所遮挡，此吋希望通过进行一个操作即可将遮挡在胎儿脸部的遮挡物去除。本实施例中，如图 7所示，在控制面板上设置一控制键（例如按钮 329) ，对应一键去除遮挡物功能，当胎儿脸部全部或部分被遮挡吋，用户通过按压按钮 329即可输入一键去除遮挡物的指令。在一种具体实施例中，一键去除遮挡物的处理流程如图 10所示，包括以下步骤： [0131] Embodiment 3: [0132] When the three-dimensional image is rotated to an angle 吋, or the three-dimensional image is observed from a certain angle of view, the flaws in the fetal face may be obscured by other structures, and thus it is desired to block the fetal face by performing an operation. The obstruction of the part is removed. In this embodiment, as shown in FIG. 7, a control button (such as button 329) is disposed on the control panel, corresponding to a button to remove the occlusion function. When the fetal face is completely or partially blocked, the user presses the button 329. You can enter a command to remove the occlusion. In a specific embodiment, a process for removing a occlusion by a key is as shown in FIG. 10, and includes the following steps:

[0139] 步骤 36，根据第一指令，降低除所述包含胎儿脸部的子集之外的其他子集对应的子图像的融合系数，从而使其他子集对应的子图像的显示效果更加透明，使得胎儿脸部图像更加凸显。 [0139] Step 36: According to the first instruction, reduce a fusion coefficient of the sub-image corresponding to the subset other than the subset of the fetal face, so that the display effect of the sub-image corresponding to the other subset is more transparent. , making the fetal face image more prominent.

[0140] 本实施例通过单一操作即可去除胎儿脸部的遮挡物，最大程度地简化了用户（例如医生）的操作。 [0140] This embodiment can remove the obstruction of the fetal face by a single operation, and the operation of the user (for example, a doctor) is simplified to the utmost extent.

[0141] 本实施例中，步骤 31-32中采用深度变化曲面的方式来区分胎儿脸部子集和其它结构的子集，本领域技术人员应当理解，在另外的具体实施例中，也可以通过其它识别方式识别出胎儿脸部子集和其它结构的子集，从而可在后续步骤 36 中降低除胎儿脸部子集之外的其他子集对应的子图像的融合系数。 [0141] In this embodiment, the depth variation surface is used in steps 31-32 to distinguish the subset of the fetal face and other subsets of the structure. Those skilled in the art should understand that, in another specific embodiment, A subset of the fetal face subset and other structures are identified by other means of identification such that the fusion coefficients of the sub-images corresponding to the subset other than the fetal face subset can be reduced in a subsequent step 36.
