Detailed Description
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
Fig. 1 is a flowchart of a method for editing a blood vessel centerline according to an embodiment of the present invention. The present embodiment is applicable to the case of editing and correcting for the extracted blood vessel centerline line. The method can be implemented by the blood vessel center line editing device provided by the embodiment of the invention, and the device can be implemented in a software and/or hardware mode and can be configured in an electronic terminal, for example, configured in a computer.
Referring to fig. 1, the method for editing a blood vessel centerline provided in this embodiment may include the following steps:
s110, receiving a center line selection operation through an editing interface; the editing interface at least comprises a first view control for presenting a curved surface reconstruction image.
Through curved surface reconstruction (Curved Projection Reformation, CPR) technology, a curve can be drawn along a region of interest, volume elements along the curve are recombined, and the twisted, shortened and overlapped vascular structures can be stretched and straightened and displayed on the same plane so as to facilitate vascular analysis. In the embodiment of the invention, the image of the central line of the blood vessel can be extracted and processed based on the CPR technology to obtain the curved surface reconstruction image. And, the curved reconstruction image may be rendered in a first view control of the editing interface.
Fig. 2 is a schematic diagram illustrating an editing interface in a method for editing a blood vessel centerline according to an embodiment of the present invention. In fig. 2, the vessel center line of the heart region is taken as an example, and description is made of information on the vessel center line editing interface. In addition, the editing interface of the vessel center line of other regions may be referred to in the related description of the embodiments of the present invention, which is not exhaustive herein. Referring to fig. 2, a curved reconstruction image may be presented in a first view control of the editing interface, and at least one vessel centerline may be included in the curved reconstruction image.
The center line selecting control can be deployed in advance in the editing interface, and the center line selecting operation can be received in response to the triggering operation of the center line selecting control so as to be used for selecting the target center line which needs to be edited currently.
For example, in some alternative implementations, where the editing interface includes a second view control for vessel navigation, receiving, by the editing interface, a centerline selection operation, including: and responding to the triggering of the vascular item control in the second view control, and receiving a center line selection operation.
Referring to fig. 2, a second view control may also be included in the editing interface, where the view control may include a vessel entry control corresponding to each vessel centerline in the curved reconstruction image. For example, the second view control of fig. 2 may include a vessel entry control (denoted by LAD in fig. 2) corresponding to the center line of the left anterior descending (left anterior descending artery, LAD) of the coronary artery of the heart, a vessel entry control (denoted by RCA in fig. 2) corresponding to the center line of the right coronary artery (right coronary artery, RCA), and the like. In addition, a plurality of sub-item controls can be arranged under each blood vessel item control so as to represent each node of the corresponding blood vessel center line, and blood vessel navigation is facilitated.
In these alternative implementations, the centerline selection operation may be considered received when a vessel entry control in the first view control is triggered. Correspondingly, the blood vessel center line corresponding to the triggered blood vessel item control can be regarded as the target center line which needs to be edited currently.
As another example, in some alternative implementations, where the editing interface includes a third view control for rendering a three-dimensional vessel image, receiving, by the editing interface, a centerline selection operation includes: and receiving a center line selection operation in response to the triggering of the vessel identification control of the three-dimensional vessel in the third view control.
Referring to fig. 2, the editing interface summary may also include a third view control that may include a three-dimensional view of the heart region including each vessel centerline and a vessel identification control for each vessel centerline. Wherein the vessel identification control may be a text control. For example, the third view control in fig. 2 may include a vessel identification control of the LAD, a vessel identification control of the RCA, or the like.
In these alternative implementations, the centerline selection operation may be deemed received when a vessel identification control in the second view control is triggered. Correspondingly, the blood vessel center line corresponding to the triggered blood vessel identification control can be regarded as the target center line which needs to be edited currently.
It will be appreciated that the second view control and/or the third view control may be provided in the editing interface to enable multiple ways of target centerline selection. And, after the target centerline is selected with one of the view controls, the associated control in the other view control will also be highlighted. For example, in fig. 2, in the case where the LAD is selected as the target center line by using the vessel entry control in the second view control, the target center line of the LAD may be displayed differently (e.g., set to different pixel values) from other vessel center lines in the third view control, so as to highlight the target center line that is currently required to be edited.
S120, selecting a target center line from the center lines of the blood vessels according to the center line selection operation, and presenting a local image containing the target center line in the curved surface reconstruction image in the first view control.
Referring again to fig. 2, after the target center line (the vessel center line of the LAD in fig. 2) to be edited is selected, the local image including the target center line in the curved surface reconstructed image may be enlarged, so that the local image including the target center line is presented in the first view control. Thereby being more beneficial to editing operation on the target center line and improving user experience.
S130, receiving a center line editing operation through an editing interface.
In the embodiment of the invention, the center line editing operation can include, but is not limited to, operations for realizing correction functions such as center line adding, deleting, cutting, extending, dragging and the like. The center line editing operation for realizing each correction function may be constituted by at least one step operation. Accordingly, at least one editing control may be deployed for each revision function in the editing interface. Further, in response to the triggering of at least one editing control corresponding to any of the correction functions, a centerline editing operation corresponding to the correction function may be received.
S140, editing pixels used for representing the target center line in the local image according to the center line editing operation.
In the embodiment of the invention, the pixels of each point in the local image belong to an editable state (namely, the pixel values can be changed). The pixels representing the target centerline may be edited in accordance with a centerline editing operation. For example, the pixel values of the pixels in the target center line can be changed to realize the correction functions such as deleting and cutting off the target center line; for another example, the pixels outside the target center line may be set to the same pixel value as the target center line, so as to increase the pixels of the target center line, and implement the correction functions of extending the target center line and adding edge branches.
According to the blood vessel center line editing method provided by the embodiment of the invention, through an editing interface, center line selection operation is received; the editing interface at least comprises a first view control for presenting a curved surface reconstruction image; selecting a target central line from all blood vessel central lines according to central line selection operation, and presenting a local image containing the target central line in the curved surface reconstruction image in the first view control; receiving a center line editing operation through an editing interface; and editing pixels used for representing the target center line in the local image according to the center line editing operation.

Fig. 5 is a schematic diagram illustrating an editing interface in a method for editing a blood vessel centerline according to a second embodiment of the present invention. Referring to FIG. 5, the "truncated centerline" mode may be entered by triggering a "truncated" control 510; a intercept point pixel may be determined from the pixels of the target centerline by dragging the index line control 520; the pixels from the cutoff point to the target centerline endpoint may be set to a preset background pixel value by triggering the "confirm" control 530 to achieve the effect of deleting a portion of the centerline from the vessel centerline.

Referring to FIG. 6, the "Add side count" mode may be entered by triggering an "Add" control 610; a second starting point pixel may be determined from the pixels of the target centerline by dragging lead control 620; the second target point pixel may be determined from the partial image by a pointing control (e.g., the arrow control in fig. 6); the second target point pixel may be validated by triggering the "validation" control 630, which may then generate a side branch centerline from the second starting point pixel to the second target point pixel, and automatically exit the "add side branch" mode after generating the side branch centerline.
Wherein the added edge branch centerline of the target centerline may be represented in fig. 6 by a dashed line. The pixels of the side branch center line can be set to be the same as the target center line, so that the pixels representing the side branch center line belong to newly added pixels for representing the target center line. In addition, the add side branch centerline may also be aborted and the "add side branch" mode exited by triggering the "cancel" 640 control or other preset shortcut key.
