Abstract

Methods and related computational techniques are presented for analyzing images from various scan modalities, such as computerized tomography ('CP'). The methods convert image values to relative differences, to highlight side-to-side asymmetry. The conversion may be performed by comparing a small region of the scan to the corresponding region in the contralateral hemisphere, quantifying the degree of relative difference using statistical techniques, and representing this quantity of relative difference in a two dimensional or three dimensional relative difference map. In exemplary embodiments the method involves assigning an axis or plane of symmetry to a medical image, computing, using the image data, at least one relative difference map based on a comparison of two substantially symmetrical areas around the 'axis of symmetry, and generating a representation of any relative difference between the two symmetrical areas. In exemplary embodiments of the present invention the 3D orientation of a volumetric representation of an organ or anatomical area can be realigned within a scanner co-ordinate system.
