1. A computer-implemented method for graphically displaying deformations, said deformations defined by comparing a first image of an object with a second image of the object, said method comprising the steps of: scanning the object twice to produce first and second images; tabulating deformations and converting said tabulated deformations into a scalar property over a preselected range; quantizing the range into a set of discrete quantization intervals; assigning a unique color out of a discrete or quasi-continuous set of colors to each quantization interval to produce a color overlay; and simultaneously displaying the color overlay and a representation of at least one of the first and second images, whereby said deformations are readily viewable in color.
