Description
Technical Field
The embodiments of the present invention relate to the field of images, and in particular, to an image generation method, apparatus, device, and medium.
Background
With the widespread use of images in various fields, the imaging speed, imaging effect, and image data storage required for generating images of images are considerable technical problems. Taking medical image imaging as an example, Volume Rendering (VR) display of blood vessels of heart, brain and other parts can provide important diagnostic basis for doctors clinically, and information such as the shape, structure, size and the like of the blood vessels can be visually and clearly displayed in front of the doctors through a three-dimensional display technology. However, due to the limitation of the scanning accuracy of the CT data and the partial volume effect, the CT value of some blood vessels adhered to bones is higher, and the blood vessels are difficult to be accurately segmented by the segmentation algorithm, so that some highlighted noise and hollow effects on the surfaces of the blood vessels can be seen in the actual VR display process, but the effect is not caused by pathological changes.
In order to eliminate as much as possible the surface pits and burrs of the blood vessels caused by partial volume effects, there are two main implementation strategies: firstly, VR and multi-planar reconstruction display (MPR) use the same volume data and mark (Mask) data, and VR and MPR are smoothed simultaneously on the display effect, specifically, the original CT value (volume data) and segmentation result (Mask data) near the surface of the blood vessel are changed by a certain smoothing algorithm, but because VR and MPR share the same volume data and Mask data, the real effect that the display result on MPR is not originally acquired is caused, and when the thickness of MPR layer is single-layer thickness, the display result is not consistent with the single-layer thickness display result at the same position in 2D; and secondly, VR displays the volume data after smoothing, MPR displays the volume data before smoothing, and the CPU and the GPU respectively store two pieces of volume data.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an image generation method according to an embodiment of the present invention. The embodiment can be applied to the situation when the images to be displayed are generated in different display scenes, and is particularly suitable for the situation when the images to be displayed are generated quickly and efficiently when the input data required for generating the images to be displayed have slight changes or the input data required for the current images to be displayed have slight changes based on the existing basic data. The method may be performed by an image generation apparatus, which may be implemented in software and/or hardware, for example, which may be configured in a computer device. As shown in fig. 1, the method includes:
s110, generating a plurality of image display instructions according to the received image display request.
Alternatively, the image display request may be a request generated according to a user operation for instructing to display an image to be displayed in the image display interface. Optionally, the image display interface may include one or more image display windows, the user may trigger different image display requests through each control in the image drawing interface, and the image generation device generates one or more image display instructions according to the image display requests after detecting the image display request triggered by the user, where each image display instruction is used to instruct to display an image to be displayed in one image display window or multiple image display windows.
In an embodiment of the present invention, the plurality of image display instructions are used to instruct to sequentially display the base image and the image to be displayed in the same display window. Illustratively, the image display device generates two image display instructions after receiving an image display request triggered by a user: a first image display instruction and a second image display instruction. The first image display instruction is used for indicating that the basic image is displayed in the appointed display window, and the second image display instruction is used for indicating that the replacement image is displayed on the basis of the basic image after the basic image is displayed in the indication display window. That is, the image display instruction in the present embodiment may be used to instruct the image display apparatus to generate the base display image from the base data, or may be used to instruct the image display apparatus to generate the image to be displayed from the base data partial replacement data.
In the present embodiment, the image generating apparatus stores therein basic data for generating a basic display image. Optionally, the basic data may be image data imported by a user, or may also be display data of an image to be displayed corresponding to a previous image display instruction generated in response to the previous image display instruction.
In another implementation manner of this embodiment, the image display instruction is configured to instruct a plurality of display windows to simultaneously display at least two display images corresponding to the display windows; the at least two display images comprise a plurality of images to be displayed, or at least one image to be displayed and the basic display image. For example, a display scene, such as a basic display or an alternative display, may be set at a position corresponding to each display window in the image drawing interface, and when a user needs to simultaneously display an image to be displayed corresponding to each display window in a plurality of display windows, the image generation apparatus detects an image display request triggered by the user by selecting each display window in the image drawing interface and selecting the alternative display scene to trigger an image display request, and generates a plurality of image display instructions after analyzing the image display request.
For example, when a user needs to display two images to be displayed simultaneously on two display windows (for example, a first image to be displayed is displayed on a first window, and a second image to be displayed is displayed on a second window), by selecting the first display window and the alternate display scene corresponding to the first display window, and the alternate display scene corresponding to the second display window in the image rendering interface, and triggering an image display request through an "image display" control, the image generation apparatus detects the image display request triggered by the user, and generates a third image display instruction and a fourth image display instruction according to the detected image display request. The third image display instruction is used for indicating that the first image to be displayed is displayed on the first window, and the fourth image display instruction is used for indicating that the second image to be displayed is displayed on the second window.
S120, aiming at least one image display instruction, determining a display scene of an image to be displayed corresponding to the image display instruction, and acquiring local replacement data corresponding to the display scene.
In the present embodiment, when the image display instruction is used to instruct generation of the image to be displayed, it is necessary to first determine the partial replacement data required to generate the image to be displayed according to the display scene of the image to be displayed. Wherein the display scene may be determined according to the image display instruction.
In an embodiment of the present invention, a display requirement may be set in an image drawing interface, and a corresponding relationship between the display requirement and a display scene may be established in advance. When an image display request triggered by a user is detected, analyzing the image display request to obtain display requirements corresponding to each image display instruction, and determining a display scene of an image to be displayed corresponding to the image display instruction according to a preset corresponding relation between the display requirements and the display scene. The display requirements are set in the image drawing interface, so that users lacking drawing experience can be assisted in drawing images meeting the display requirements.
For example, when the image to be displayed is a medical image, the display requirement may be to display a volume rendering image or to display a two-dimensional image, and correspondingly, the display scene may include displaying an original image or displaying an optimized image, and a drop-down frame may be set in the image rendering interface for enabling a user to select the display requirement to display the volume rendering image or to display the two-dimensional image. After an image display request triggered by a user is received, determining a display scene of an image to be displayed according to a display requirement carried in the image display request and a preset corresponding relation between the display requirement and the display scene. For example, when the image to be displayed is a blood vessel image, the display scene corresponding to the image to be displayed is an optimized image when the display requirement is a volume rendering image, and the display scene corresponding to the image to be displayed is an original image when the display requirement is a two-dimensional image.
In an embodiment of the present invention, a display scene may be directly set in the image drawing interface, and when an image display request triggered by a user is detected, the image display request is analyzed, so as to directly obtain the display scene corresponding to each image display instruction. The display scene is directly set in the image drawing interface, so that the image generation step can be simplified, and the image generation speed is increased.
In this embodiment, a corresponding relationship between the display scene and the local replacement data may be preset, and after the display scene of the image to be displayed is determined, the local replacement data corresponding to the image to be displayed is determined by searching the preset corresponding relationship. Optionally, the partial replacement data includes: difference data of a plurality of image data or processing data of one image.
In an embodiment of the present invention, if each image to be displayed, which is required to be displayed through multiple display windows by a user, is an image in a different display scene corresponding to the same original data, the local replacement data is original data or processed data of an image, and specifically, the local replacement data may be local original data or local optimized data.
In an embodiment of the present invention, if the images to be displayed, which are required to be displayed through the plurality of display windows by the user, are different images corresponding to different original data, the local replacement data may be difference data between the plurality of image data. Illustratively, if a user needs to display a first image through a first window and display a second image through a second window, comparing the first image raw data with the second image raw data to determine an area with different data values of corresponding voxel points between the first image raw data and the second image raw data, taking the area as a difference area, combining data corresponding to the difference area in the first image raw data as first difference data, and combining data corresponding to the difference area in the second image raw data as second difference data. Alternatively, the partial replacement data may be the first difference data or the second difference data.
And S130, generating an image to be displayed based on the current basic data and the local replacement data.
In this embodiment, the current basic data may be image data selected or imported by the user through the image drawing interface, or image data already existing in the image generating apparatus (e.g., display data of an image to be displayed corresponding to a previous image display instruction generated in response to the previous image display instruction).
In the present embodiment, the image generating device may be a Central Processing Unit (CPU) or a Graphics Processing Unit (GPU). Generally, a CPU receives an image display request triggered by a user and generates a plurality of image display instructions, and then determines a display scene of an image to be displayed and partial replacement data of the image to be displayed based on the image display instructions. Optionally, after determining the local replacement data of the image to be displayed, the image may be drawn at the CPU end, or the data may be uploaded from the CPU end to the GPU end, and the image may be drawn at the GPU end. That is, the operation of generating the image to be displayed based on the current basic data and the local replacement data may be performed by the CPU side or the GPU side. Therefore, when the image is drawn, the drawing of the image can be completed only by respectively reserving a complete volume data and a local replacement data at the CPU end and the GPU end, the drawing efficiency of the image is improved, and the occupation of a CPU memory and a GPU video memory is reduced.
Optionally, the generating an image to be displayed based on the current basic data and the local replacement data includes:
and generating display input data of the image to be displayed based on the current basic data and the local replacement data, and generating the image to be displayed according to the display data.
Wherein the generating display data of the image to be displayed based on the current basic data and the local replacement data comprises:
and for each voxel point in the local replacement data, replacing the data value corresponding to the voxel point in the current basic data by using the data value of the local replacement data corresponding to the voxel point, and using the complete volume data after data value replacement as the display input data of the image to be displayed.
Specifically, the current basic data includes position coordinates of each voxel point and a data value of each voxel point, and the local replacement data includes position coordinates of each local voxel point and a data value of each local voxel point. Optionally, the voxel point in the current basic data corresponding to each local voxel point may be determined according to the position coordinate of the local voxel point, the data value of the local voxel point is used to replace the data value of the voxel point with the same position coordinate, the replaced volume data is generated, and the replaced complete volume data is used as the display input data of the image to be displayed.
After the display input data of the image to be displayed is determined, the image to be displayed is generated according to the image generation instruction and the display input data, the display input data can be used as the basic data of the next image generation instruction, so that when the next image generation instruction is responded, the display input data of the image to be displayed corresponding to the next image generation instruction is generated based on the basic data and the local replacement data corresponding to the next image generation instruction, the display input data of the image to be displayed corresponding to the current image generation instruction is used as the basic data of the image to be displayed corresponding to the next image generation instruction, the occupation of memory and display memory resources is saved when the image to be displayed is generated under the condition that the image data of the image to be displayed corresponding to each image generation instruction has slight change, and the image display efficiency is improved. Optionally, the image to be displayed may be generated in an existing image generation manner, which is not described herein again.
The embodiment of the invention generates a plurality of image display instructions according to the received image display request; determining a display scene of an image to be displayed corresponding to at least one image display instruction, and acquiring local replacement data corresponding to the display scene; and generating an image to be displayed based on the current basic data and the local replacement data, so that the display effect and efficiency of the image are improved, and the occupation of an internal memory and a display memory is reduced.
On the basis of the above scheme, after the image to be displayed is generated, the method further comprises the following steps:
and determining a display window of the image to be displayed corresponding to the image display instruction according to the image display instruction, and displaying the display image on the display window.
In this embodiment, the display window carried in the image display instruction is obtained by analyzing the image display instruction, and after the image to be displayed is generated, the image to be displayed corresponding to the image display window is displayed on the display window.
Example two
Fig. 2 is a flowchart of an image generation method according to a second embodiment of the present invention. The present embodiment is further optimized on the basis of the above-described embodiments. As shown in fig. 2, the method includes:
s210, a plurality of image display instructions are generated according to the received image display request.
S220, aiming at least one image display instruction, determining a display scene of an image to be displayed corresponding to the image display instruction, and acquiring local replacement data corresponding to the display type according to the corresponding relation between the display scene and the local replacement data.
And S230, generating an image to be displayed based on the current basic data and the local replacement data.
In the present embodiment, the image is embodied as a medical image. For example, when the image to be displayed is a blood vessel image, the current basic data may be blood vessel image data imported by a user, or may be display data of the blood vessel image to be displayed corresponding to a previous image display instruction generated in response to the previous image display instruction.
When the image to be displayed is a medical image, the display scene may be an original image or an optimized image. Wherein, the optimized image can be a smooth image or an enhanced image.
For example, when the medical image is a blood vessel image, the optimized image may be a smooth image. In view of the fact that when the blood vessel image data is smoothed, the smoothed volume data is only a blood vessel surface portion in a physical structure and usually only occupies a small portion of the whole volume data, in this embodiment, only one set of complete volume data and local volume data may be saved in the image generating apparatus, where the local volume data is the local volume data before smoothing or the local volume data after smoothing, when the blood vessel display is performed by volume rendering, the complete original volume data is locally updated by using the local volume data after smoothing, the complete smooth data is generated, and the image rendering is performed based on the generated complete smooth data, so as to achieve the smooth blood vessel display effect. After volume rendering is carried out, when multi-plane reconstruction display is carried out, discrete volume data before smoothing is used for locally updating complete smooth data to generate complete original data, and image rendering is carried out based on the generated complete original data to achieve the original image display effect. The complete data is updated through the local data, so that the display effect is ensured, the occupation of the memory and the display memory by two complete data is avoided, and the method has important significance for saving the performance of the whole system.
Alternatively, the image generating device may be a Central Processing Unit (CPU) or a Graphics Processing Unit (GPU), and the image may be drawn on the CPU or the GPU. For example, only one volume data may be stored in both the CPU memory and the GPU memory, then one discrete data before and after smoothing is stored at each of the CPU and the GPU terminals, and when performing volume rendering vascular display, the original volume data is locally updated at the GPU terminal using the smoothed discrete data to generate smoothed volume data, so that the rendered image achieves a smooth vascular display effect.
Illustratively, when a user needs to simultaneously display a three-dimensional optimized blood vessel image generated by volume rendering and a two-dimensional original blood vessel image generated by each surface rendering in a plurality of windows, an image display request is triggered through an image rendering interface, and an image generation device generates a volume rendering image display instruction and a surface rendering image display instruction according to the received image display request.
And aiming at the volume rendering image display instruction, determining a display scene corresponding to the volume rendering image display instruction as a display smooth image, acquiring local smooth data corresponding to the image after display optimization as local replacement data of the volume rendering image to be displayed, generating complete smooth data based on the local smooth data and current basic data (complete original data), drawing a volume rendering blood vessel image according to the complete smooth data, and taking the complete smooth data as basic data of a surface rendering blood vessel image corresponding to the surface rendering image display instruction.
And aiming at the surface drawing image display instruction, determining a display scene corresponding to the surface drawing image display instruction as a display original image, acquiring local original data corresponding to the display optimized image as local replacement data of the surface drawing image to be displayed, generating complete original data based on the local original data and current basic data (complete smooth data), and drawing a surface drawing blood vessel image according to the complete original data.
According to the technical scheme of the embodiment of the invention, the image to be displayed is embodied into the medical image on the basis of the embodiment, on the basis, the display scene of the image to be displayed corresponding to the image display instruction is determined, the local replacement data corresponding to the display scene is obtained, the image to be displayed is generated to be embodied on the basis of the basic data and the local replacement data of the image to be displayed, the basic data is replaced by the local original data or the local optimization data, the display input data of the image to be displayed is generated, the image drawing effect of volume drawing or surface drawing of the blood vessel image is improved, and the occupation of the memory and the display memory by two complete volume data is avoided.
Fig. 2b is a schematic drawing diagram of a drawing effect of drawing a blood vessel image by using the image generation method provided by the second embodiment of the present invention. Because the two-dimensional image is not boned, smooth optimization is not performed when the two-dimensional image is displayed; the three-dimensional volume rendering image is only used for observing blood vessels, so that smooth optimization is required after the bone structure is removed.
In one embodiment of the present invention, the basic data is original volume data of the blood vessel image, the local replacement data is locally optimized data, and the top left corner image in fig. 2b is a blood vessel optimized three-dimensional volume rendering image generated from the basic data and the local replacement data based on the image display instruction; the remaining three images are three two-dimensional images generated from the base data.
In another embodiment of the present invention, the basic data is smooth volume data of a blood vessel image, the local replacement data is original volume data (i.e., local original data) corresponding to an optimized portion, and the upper left corner image in fig. 2b is a blood vessel optimized three-dimensional volume rendering image generated based on the basic data; the remaining three images are original two-dimensional images of the blood vessel generated from the basic data and the local replacement data based on the image display instruction.
