The First North American Clinical Gamma Knife Center.

A decision to develop a stereotactic radiosurgery center and install the first 201 cobalt-60 Gamma Knife in Pittsburgh was made in 1981 after gathering regional and leadership support. This was part of a 7-year quest that required overcoming barriers to a new technology unfamiliar to US regulatory authorities and insurance companies. The first patient was treated in August 1987. Since that time our center has installed each succeeding Gamma Knife device developed. During an initial 30-year experience we performed more than 14,750 patient procedures. In addition to patient care our Center's goal was to develop a major teaching and clinical research program that eventually led to the training of more than 2,500 physicians and medical physicists, the publication of more than 600 peer-reviewed clinical outcome research studies, and 4 books. This report summarizes the rationale for acquisition, the challenges and the early years, and then the evolution of our center which installed the first US 201 source Gamma Knife.
