When medical patients need imaging more sophisticated than the common X-ray, they can thank Robert S. Ledley, a dentist who became a professor of physiology, radiology and biophysics at Georgetown University, where he invented the whole-body CAT (CT) Scan scanner.
This new kind of scan provided three-dimensional images and was first used for cancer patients. This technology allowed physicians to look at their patients' internal organs without surgery. It has been of particular use in finding tumors and blood clots or other obstructions.
Dr. Ledley got his patent for the CAT-Scan in 1975. He now holds more than 60 patents.
