A new cell projection algorithm based on feature region of 3D medical data field

Considering the fuzzy characteristics of medical data field and requests of practicability, the paper presents a novel cell projection algorithm based on edge transition region of medical, 3D data field. First, 3D data field is pretreated to a unitary and integral field, and the paper extends the method of segmenting 2D image and makes it can be used to extract edge transition region of 3D data field. Then, the edge transition region and the non-edge transition region are projected separately. Last, the realization and experiment results show that the algorithm can improve image quality of edge transition region and guarantee rendering speed effectively.
