Clinical Applications of Spectral Photon Counting Computed Tomography Technology

Salim Aymeric Si-Mohamed, MD, PhD, is a full professor in medical imaging at the University Claude Bernard Lyon 1 and head of the Cardiovascular and Thoracic Imaging Department at Louis Pradel Hospital in Lyon. Specializing in diagnostic and interventional imaging for cardiovascular and thoracic diseases, he primarily works with cutting-edge CT technology. Dr. Si-Mohamed's experimental research focuses on the development of spectral CT technology, including spectral photon-counting CT and dual-energy CT systems, integrated with novel contrast agents for cardiovascular and thoracic applications. He earned his MD in 2016 and completed his PhD in 2020, with his doctoral research dedicated to the cardiovascular applications of spectral photon-counting CT technology. His groundbreaking work demonstrated the feasibility of color K-edge imaging for cardiovascular imaging, particularly in studying atherosclerosis. Dr. Si-Mohamed is an active member of several national and international research consortia, fostering multidisciplinary collaborations among academic, university, and industry partners. He has authored over 150 publications in leading international journals and conferences, focusing on both experimental and clinical spectral CT imaging. Dr. Si-Mohamed teaches the principles, techniques, and applications of spectral CT, mentoring MSc and PhD students. He is also the holder of an international patent. In 2023, he was awarded an ERC Starting Grant for the KOLOR SPCCT Imaging Project, aimed at advancing comprehensive, one-breath-hold imaging of lung diseases using color K-edge imaging and dedicated contrast agents.
