History and Innovators COOK
CHARLES T. DOTTER (1920-1985), was born in Boston, Massachusetts. He studied medicine and radiology at Cornell University, where he served in a staff position from 1950 to 1952. He then served as Professor and Chairman of Radiology at the University of Oregon Medical School for 33 years until his death.

Dr. Dotter altered the course of cardiovascular radiology and is considered the father of interventional radiology. He began modifying the Seldinger technique for therapeutic purposes. This first therapeutic use of the Seldinger technique quietly started a medical revolution: simultaneous diagnostic and therapeutic procedures reduced the number of surgical beds needed, patient risk and the length of patient stay. Costly and traumatic surgical procedures were eliminated in many cases. These benefits proliferated as the technique extended into other areas of medicine.

Dr. Dotter first described transluminal angioplasty in 1964. While skepticism reigned in the United States, European radiologists institutionalized the term, "Dottering" of patients. Dotter's pioneering work and vision are reflected in four gold medals in radiology and, in 1978, a nomination for the Nobel Prize in Medicine.
