50th Anniversary of CT at Mayo Clinic Scientific Symposium
Monday, June 19th, 2023
On June 19, 1973, the first patient CT scan in North America was performed at St Marys Hospital in Rochester, MN. The 50th Anniversary of CT at Mayo Clinic Scientific Symposium was held 50 years later to the day, with the original scanner right in the building. See below for a documentary about that first scan (which premiered live at the Symposium), as well as recollections from original Mayo staff present at the start of this revolution in medicine, and lectures from leading CT scientists whose vision and ingenuity have helped shape the field as we know it today.
Building on the rich legacy of scientific discovery and clinical research at Mayo Clinic, the Mayo Clinic CT Clinical Innovation Center was founded in 2004 to develop and translate high-impact CT technical innovations into patient care. The Center, along with the Department of Radiology, and each member of our respective teams – physicians, scientists, engineers, research fellows, and trainees –welcome you to enjoy the Symposium!
