Displaying of Details in Subvoxel Accuracy

Under the volume segmentation in voxel space, a lot of details, some fine and thin objects, are ignored. In order to accurately display these details, this paper has developed a methodology for volume segmentation in subvoxel space. In the subvoxel space, most of the "bridges" between adjacent layers are broken down.Based on the subvoxel space, an automatic segmentation algorithm reserving details is discussed. After segmentation, volume data in subvoxel space are reduced to original voxel space. Thus, the details with width of only one or several voxels are extracted and displayed.
