Charles Theodore Dotter (14 June 1920 – 15 February 1985) was a pioneering American radiologist who is credited with developing interventional radiology.
He went to medical school at Cornell, where he met his future wife, Pamela Beattie, a head nurse at New York Hospital.
It was Dotter who, in 1950, developed an automatic X-Ray Roll-Film magazine capable of producing images at the rate of 2 per second.
After successful dilation of the stenosis with a guide wire and coaxial Teflon catheters, the circulation returned to her leg.
He served as the chairman of the School of Medicine Department of Diagnostic Radiology at Oregon Health Sciences University for 33 years, from 1952 until his death in 1985.
