COMP Imaging Lecture Series- Lecture 5: Photon counting CT with Dr. Mikael Simard – March 28th, 1-2pm EST
Fundamentals of spectral photon-counting CT
Spectral photon-counting CT (SPCCT) is a rapidly developing X-ray modality that allows CT systems to count photons in discrete energy bins rather than integrating the signal over all photon energies. Prototype systems promise improved image quality and tissue quantification, reduced dose and open the possibility of multi-contrast imaging.
In this lecture, the fundamentals of SPCCT will be covered, from detectors to material decomposition methods, focusing on how the technology allows improved image quality and tissue quantification. The current state of the technology towards clinical adoption will be discussed.
Examples of research work conducted with a Medipix All-Resolution System (MARS) SPCCT at the University of Montreal will be reported, with a focus towards potential applications in radiotherapy. Research from other groups focused on radiological applications will also be summarized.

Mikaël completed his PhD on the use of photon counting CT for radiation therapy in 2021 at University of Montreal under the supervision of Hugo Bouchard. He has significant expertise in image reconstruction for quantitative applications. He is now a Marie-Curie postdoctoral fellow at University College London, and working on novel algorithmic developments for proton imaging.
