Abstract: Medical image surface reconstruction is an important assistant method helping doctors diagnose the inner disease of human body.To raise the speed of reconstruction，a new fast surface-reconstruction method is proposed based on a reserve Shear-Warp method and a boundary-voxel-based fast method.Unnecessary data processing will be cut down by reverse Shear-Warp method and the whole boundary voxels will be obtained without tracing through the whole data field as previous method by a method that abstracts boundary voxels in two total opposite directions.These volume data will be used repeatedly so that it is not necessary to re-trace through the whole data field.The efficiency of using boundary voxels is raised and so the purpose of fast reconstruction is achieved.

Key words: fast reconstruction, reverse Shear-Warp, boundary voxels
