Problems solved by technology

[0005] The 3D region of interest changes arbitrarily with the editing of the graphics on the 2D plane, which is quite different from the region of interest that the user wants to generate through editing, resulting in errors in the statistical information of the 3D region of interest

Abstract

The invention provides a method and device for determining an area of interest of a medical image and an image editing system, relates to the image processing technology field, makes the shape and / or the position of the area of interest change along with a transformation matrix and finally makes the generated shape and the position of the area of interest be more accurate. The method comprises steps that an initial graph generated during intersection of an initial area of interest and a plane is acquired, and a final graph generated after editing the initial graph is further acquired; a transformation matrix of transformation of the initial graph into the final graph is acquired; according to the transformation matrix, the shape and / or the position of the area of interest is modified to acquire the final area of interest. The method is advantaged in that the method is suitable for fusion applications or tumor tracking applications for the statistics information of the area of interest.

Description

【Technical field】 [0001] The invention relates to the technical field of image processing, in particular to a method, device and image editing system for determining a region of interest in a medical image. 【Background technique】 [0002] In applications such as fusion applications and tumor tracking, users draw graphics on the plane to obtain the corresponding 3D region of interest (also known as VOI, Volume of Interest, a specific 3D region of interest), through the 3D region of interest Perform statistical analysis or lesion segmentation for disease treatment. However, the 3D region of interest obtained by the user for the first time may not contain all the pathological regions, that is, it cannot meet the user's needs. Therefore, it is necessary to edit the graphics generated by the intersection of the 3D region of interest and the 2D plane to modify the 3D region of interest. shape and / or location. [0003] At present, the shape and / or position of the three-dimensiona...
