Embodiment Construction
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0039] The invention discloses a method for cutting human body tomographic data, the flow chart of which is as follows figure 1 shown, including:
[0040] Step S11, storing multiple tomographic images;
[0041] Among them, the multiple tomographic images stored are tomographic images of multiple cross-sections, that is, the original images collected, that is, after the human body is frozen and fixed, the plane cutting is performed by the machine...

The invention discloses a human tomographic image cutting method and system. The method is characterized by storing a plurality of tomographic images and forming a three-dimensional digital human body image; receiving a cutting command, and generating a cutting surface according to the cutting command; calculating 3D coordinate of each pixel point of the three-dimensional digital human body image in the space; judging whether the 3D coordinate of each pixel point locates on the back surface of the cutting surface; if not, setting the color of the pixel point to be transparent; and generating cutting tomographic images corresponding to the cutting command according to the color display of each pixel point. According to the scheme, the plurality of tomographic images form the three-dimensional digital human body image, and the three-dimensional digital human body image is cut, so that the cutting tomographic images at various angels can be formed, but not just images in three directions are formed; and besides, spatial positions of the tomographic images in the human body can be obtained according to the 3D coordinate of each pixel, but not just a piece of isolated plane image is formed.
Description
technical field [0001] The invention relates to the technical field of cutting, in particular to a method and system for cutting human body tomographic data. Background technique [0002] With the development of medical science, more and more attention has been paid to anatomy teaching in the teaching field. At present, when dissecting digital humans through computers, tomographic image data are generally required. [0003] At present, when rendering digital humans, surface rendering is usually used. Generally, the boundary segmentation is performed on the RGB tomographic image of the human body to determine the boundaries of human tissue, and then use tools to generate corresponding triangular surfaces according to the boundaries. Finally, Form the surface models of various tissues and organs of the human body. [0004] However, surface rendering usually sees tissue surface information. In order to be able to see the internal information of tissues and organs, data from th...
