Facilitating innovations in imaging

Our center develops, optimizes and translates innovative CT technologies into practice to improve patient care.


The mission of the CT Clinical Innovation Center at Mayo Clinic is to facilitate high-impact imaging innovations that translate directly into patient care.

Our center develops and evaluates new computerized tomography (CT) technology, clinical applications and dose-reduction techniques.

Our core team of researchers and clinical investigators in the CT Clinical Innovation Center has particular expertise in the use of computerized tomography for quantitative assessment of disease progression and regression, organ function, material compositions, and methods to quantify and reduce radiation dose.

Our center also provides Mayo Clinic investigators with access to cutting-edge CT technology, CT physics support and consultation, and advanced image processing capabilities. We also now offer the Patient CT Projection Data Library, which has data from hundreds of patient scans, including patient CT exams of the head, chest and abdomen, cases from Siemens scanners and cases from GE scanners.


The director of the CT Clinical Innovation Center is Cynthia H. McCollough, Ph.D. Dr. McCollough is an internationally renowned researcher in the development and evaluation of CT technology and dose-reduction methods. She is a professor of both medical physics and biomedical engineering at Mayo Clinic College of Medicine and Science in Rochester, Minnesota. Dr. McCollough's work focuses on maximizing the benefit and minimizing the risk of computerized tomography. She and her team are developing ways to keep radiation exposures as low as possible, while maintaining the needed image quality.

The center's medical director is Joel G. Fletcher, M.D. Dr. Fletcher is a gastrointestinal radiologist and a leader in the Department of Radiology's Division of Abdominal Imaging at Mayo Clinic in Rochester, Minnesota. Dr. Fletcher's research interests include CT imaging, pancreatic cancer imaging, dynamic pelvic floor imaging, and imaging in Crohn's disease and other small bowel disorders.
