François Therriault-Proulx, PhD, Co-founder and CEO, Medscint inc.

Medical physicist, researcher and entrepreneur, Francois co-founded Medscint in 2018 and is currently president and CEO of the company. This early-stage company, based in Quebec City, is specialized in the development of scintillation dosimetry solutions for radiation-oncology. In 2019, the company won the OSEntreprendre Startup Business Grand Prize in the category “Technological and Technical Innovations”. Prior to co-founding the company, Francois obtained his PhD in Physics from Université Laval (2008-2012) and was an Odyssey postdoctoral Fellow at University of Texas MD Anderson Cancer Center (2013-2015). In 2012, he won the « J.R. Cunningham Young Investigator Award » from the COMP as well as a « Best in Physics » prize from AAPM. With an expertise in plastic scintillation dosimetry, he is co-author on 25 scientific publications, two patents, and two book chapters.

In addition to his academic resume, Francois has taken part in multiple entrepreneurship training programs in both US and Canada (NSF I-CORPS, Académie de la Relève Entrepreneuriale, Medical Alley Bootcamp, Rice Ignite Entrepreneurship Trek) and is also an active member of Quebec Vitae, an organization specialized in life science and medical devices. Francois is also president of the board for the University Laval Rouge & Or X-Country and Track and Field team.

Plastic scintillation detectors in radiation therapy: The Future of Dosimetry is Optical

Whether it is because they are small, flexible, made of water-equivalent material or show good energy independence for megavoltage photon and electron beams, plastic scintillation detectors (PSDs) show great promises for multiple applications in radiation therapy. With its commercially available multi-channel plastic scintillation dosimetry research platform called the Hyperscint (HS-RP200), Medscint is providing medical physicists with a first all-inclusive versatile real-time scintillation dosimetry solution. Based on a hyperspectral patented technology, the Hyperscint allows for full Cerenkov and fluorescence removal, which is key to accurate dosimetry in various conditions.

In this presentation, the basics of scintillation dosimetry will first be discussed before presenting some of the latest research results involving the Hyperscint, including applications for 1) small-field dosimetry, 2) MR-Linacs, and 3)FLASH/UHDR radiation therapy. Future perspectives for PSDs will also be presented.
