METHOD FOR INTERACTIVE THRESHOLD SEGMENTATION OF MEDICAL IMAGES

摘要

A method of delineating a region of interest in a medical image and a system for carrying out this method is disclosed. The method provides selecting an initial point on a desired region of interest in the image. The initial point corresponds to a voxel having an initial voxel intensity. An initial range of voxel intensities is identified which includes the initial voxel intensity. A preliminary region of interest that includes the initial pixel and all connected pixels having a signal intensity in that initial range is delineated and displayed on the image. The initial range of signal intensities is adjusted based on user feedback. An adjusted region of interest is displayed. Also disclosed is a method of quantitatively analyzing a desired parameter in a region of interest of a medical image in real time and a system for carrying out this method. The method provides calculating a parameter within a preliminary region of interest, and displaying a calculation in real time. The parameter may be recalculated upon adjustment of the region of interest.
