Volume rendering method and volume rendering system for human body tomography data

Abstract

The invention discloses a volume rendering method and a volume rendering system for human body tomography data. Through directly receiving an image reading instruction, corresponding tissue and organ information is searched according to the image reading instruction through indexing. The searched tissue and organ information is loaded into a three-dimensional texture in a layered manner. Light projection is performed in a GPU, thereby rendering a three-dimensional image of the tissue and organ. According to the volume rendering method and the volume rendering system, through performing light projection on the image of the tissue and organ in the GPU, a real-time rendering effect can be realized by means of programmable image hardware. Furthermore, according to the volume rendering method and the volume rendering system, through loading the stored tissue and organ information into the three-dimensional texture in the layered manner, the three-dimensional image is formed, and a dynamic whole image in different angles is output, thereby preventing a static image which is output by means of a third-party open source database or three-dimensional reconstruction software, and improving real-time performance in image rendering.

Description

technical field [0001] The present invention relates to the technical field of rendering, in particular to a method and system for volume rendering of human body tomographic data. Background technique [0002] With the development of the medical industry, more and more attention is paid to anatomy teaching in the teaching field. At present, when rendering digital humans through computers, surface rendering technology is generally used. [0003] Surface rendering is to cut the boundary of the RGB tomographic image of the human body to determine the boundary of the human tissue, and then use tools to generate the corresponding triangular surface according to the boundary, and finally form the surface model of each tissue and organ of the human body. [0004] However, the image rendered by the surface rendering technology does not have a strong sense of reality, and the surface rendering technology can only display the outer surface of the human organ, while the inner surface o...
