Paper Abstract

A simple technique has been developed to simultaneously display regions of a CT image which have large differences in CT numbers, such as lung and soft tissue. The CT image is considered to be the sum of two unimodal distributions of CT numbers and the CT numbers associated with one region are mapped into the other using a simple linear transformation. The significance of this technique is that it permits the entire CT image to be visualized with optimum contrast either on the CT display monitor or on a single photograph. Examples of a body section and a head section are presented.
