Abstract

The invention discloses a medical image volume rendering method and a device thereof. The method comprises the following steps: firstly, volume data are loaded into a display memory, and volume data textures corresponding to different tissues are generated; a transmission function corresponding to each tissue is created; and an image corresponding to each tissue is respectively rendered by utilizing the transmission function and the volume data textures. The invention can be utilized to improve the rendering speed and the rendering quality.

Description

technical field

[0001] The invention relates to volume rendering technology, in particular to a medical image volume rendering method and device. Background technique

[0002] Volume rendering, also known as direct volume rendering, is a 3D data field visualization method that has developed rapidly in recent years. Volume rendering does not generate intermediate primitives, and directly generates a two-dimensional image of the screen from a three-dimensional data field. First, the initial continuous three-dimensional data field is obtained by reconstructing the discrete three-dimensional data field, and then resampled in the continuous three-dimensional data field to obtain the function value of the sampling point. For new sampling points, classification and color assignment are carried out according to the set opacity and color model, and finally the rendering result image is obtained through image synthesis according to the volume rendering optical model.
