Abstract

We propose a method for improving the visualization of potential target regions in radiographic projection images. This is accomplished by modifying the intensity lookup tables (LUT) to compensate for, (1) cathode ray tube (CRT) dynamic range limitations and, (2) for contrast sensitivity characteristics of the human eye. We match the resulting LUT to selected regions of the image to optimize the use of the available intensity range.
