Abstract:
A method for displaying region extracting processing an image processing system to perspectively project 3-dimensional voxel data onto a 2-dimensional display, said method comprising the steps of:executing a connected region expanding process onto 3-dimensional voxel data of an object to extract a region corresponding to a substructure of said object from said 3-dimensional voxel data, said connected region expansion process starting from a seed voxel and including automatic repetitions of an expansion substep wherein a plurality of voxels are incorporated into extracted voxels on the condition that said voxels are adjacent to previously incorporated voxels and satisfy expansion criteria;executing 3-dimensional perspective projection process onto extracted voxels after each repetition of said expansion substep is completed to generate and renew image data for a perspective projection image successively; anddisplaying the perspective projection image onto the 2-dimensional display in a realtime manner simultaneously with repetitions of said expansion substep.
