Abstract: Based on volume rendering technology, this paper puts forward a new idea of volume transparency analysis. It gives many algorithms including volume segmentation algorithm and enhancement contrast algorithm of volume data based on generalized fuzzy rough sets GFRS, and studies the application of the algorithms above. The volume transparency analysis system making use of interactive data language IDL6.2 is implemented. The successful test of the system with the first American and the first Chinese human body data indicates the value in theory and practice and wide market of the system.
