【Abstract】 This paper discusses the 3D visualization techniques of medical volume data. Combined the two traditional algorithms, surface rendering and volume rendering, hybrid rendering is employed to the reconstruction from 2 D MRI sequences to 3 D object and slice data indexing technology of MRI sequence reconstruction is present in detail. This kind of method solves the problem that inner data is invisible by surface rendering. Computation speed is faster than volume rendering. From the interactive linear interpolation of interlayer data, the pathological characteristics such as shape, size and color distribution are observed in arbitrarily oriented places or curved sectionings, which are very helpful for clinical diagnosis.更多还原
