ORGAN-SPECIFIC ENHANCEMENT FILTER FOR ROBUST SEGMENTATION OF MEDICAL IMAGES

摘要

An imager (10) and a reconstruction processor (12) generate an intensity image (14). A region containing a target volume is identified (20) and limited (24). A classifier (30) operates on the voxels in the limited volume with an enhancement filter to generate an enhanced image, such as an image whose voxel values represent a probability that each voxel is in the target volume. A segmentation processor (40) segments the enhanced image to identify the surface of the target volume to generate a segmented image which is displayed on a monitor (52) or used in a radiation therapy planning system (54).
