In the Chinese patent titled "System and Method for Interactive Definition of Region of Interest and Space", publication number CN101405764, ROI or VOI is defined in terms of shape and size, and the shape is determined according to the value adjusted by the mouse. It is obtained by threshold extraction. The function of size is to limit the shape to a specific size range. Combining the two aspects of shape and size, this invention allows users to interactively adjust ROI or VOI, even in images with certain noises. , can also obtain the target region of interest; this invention is actually an interactive threshold value extraction method, which belongs to the field of image segmentation technology, and has little correlat

[0066] see figure 2 , in the third embodiment of the present invention, the processing module 20 includes:

[0067] The first processing sub-module 21 is configured to use the intersection points of the six planes of the cuboid bounding box and the projection rays as the starting point and endpoint; and / or

[0068] The transformation sub-module 22 is used to transform the six plane equations of the cuboid bounding box into the visual coordinate system when the scene of the three-dimensional medical image / graphic display includes surface rendering;

[0069] The second processing sub-module 23 is used to dot-multiply all the plane equations in turn after each vertex of the surface model is transformed into the visual coordinate system; in the process of dot-multiply in turn, a dot-multiply result appears is negative, no display processing will be performed on the vertex; and / or

Abstract

The invention belongs to the technical field of medical images and provides an interactive method for 3D medical image/graphic display and a system thereof. The method includes selecting an interactive processing range through controlling a bounding box in a 3D medical image/graphic display scene; applying the range delineated by the bounding box to the 3D medical image/graphic display processing to obtain the corresponding local display result; and outputting the local display result to a segmentation algorithm and exerting corresponding segmentation processing. Therefore, local display for regions of interest and regions of space under a display mode is achieved.

Description

technical field [0001] The invention relates to the technical field of medical images, in particular to an interactive method and system for graphic display of three-dimensional medical images. Background technique [0002] A 3D medical image is an image sequence obtained from medical imaging equipment such as ultrasound, nuclear magnetic resonance, and CT, and is usually represented in a three-dimensional pixel matrix. The surface model with medical significance obtained from 3D medical images using image segmentation, reconstruction and other technologies is called 3D medical graphics. [0003] Volume rendering is a visualization technique that simultaneously displays all volume details of a 3D image. By setting the opacity transfer function, color transfer function and gradient transfer function in volume rendering, pixels with different gray values ​​can display different display effects, thus presenting internal information and spatial volume details. [0004] Surface...
