Although established in 2000, the RSEA was formally incorporated in 2002 with the charge of being a professional, technical, and educational nonprofit organization dedicated to serving the needs of service engineers specializing in radiotherapy systems.

In the late 90’s, the American Association of Physicists in Medicine (or AAPM) recognized the need for an independent engineer association in the late 90’s.  Dr. Kenneth Hogstrom, Chief Physicist at MD Anderson led the effort as the President of AAPM. He created a committee to help organize in-house engineers. This effort led to the RSEA’s introduction to the oncology community in Chicago at the 2000 AAPM annual meeting. The interest in the RSEA was immediate, with over 40 engineers joining that meeting. We sincerely appreciate the trust and support from the AAPM community – it is an integral connection to the RSEA’s past, present, and future success.
