    Like the spellcheck program on a word processor, which helps writers avoid typographical errors, the aim of this project is to develop a CAD program that provides "another set of 'eyes' in reviewing images, alerting a radiologist to look closer at specific areas of an image," according to Dr. Martin J. Lipton, chairman of the Radiology Department at the University of Chicago Medical Center, where the CAD technology is being developed.
