Mathematics and Statistics Colloquium (Oct 30)
Speaker: Dr. Sree Bash Debnath (Assistant Professor, Department of Radiation Oncology, Stritch School of Medicine, Loyola University Chicago)
Time and Location: Thursday, October 30, 2025. 4-5pm at IES 110 (refreshment 3:00pm on the 5th floor of BVM)
Title: Advancing Cancer Therapy: Innovations in Radiation Detection and Dosimetry
Abstract: Cancer, a leading cause of death worldwide, and the treatment systems rely extensively on advanced imaging—the computational process of creating visual representations from data—for diagnosis and radiation therapy techniques. However, it remains a significant global challenge in the current medical technology due to the lack of appropriate dosimetry—the science and practice of measuring and calculating radiation dose—and advancement in imaging. The advancement of modern radiation therapy is driven by the ongoing demand for effective detector technologies capable of accurate dose measurement and quality assurance across diverse radiation beam treatments (photon, proton, electron, ion, etc.). In this context, we focus on developing a novel, highly sensitive radiation detection approach through device geometrical modeling, while introducing innovative micro-dosimetry methodologies to advance quantitative dose measurement. These new devices and techniques aim to enhance small-field beam treatments, beam modeling, dose calculations, and characterizing ultra-high dose rate FLASH radiation. In addition, the development and algorithmic modeling of an AI-integrated imaging system will be discussed for advanced imaging applications. This research aims to transform radiation dosimetry by enhancing treatment quality, improving the understanding of the effects of ionizing radiation on tissues, and pioneering high-resolution imaging technologies (e.g., X-ray/γ-ray cameras), thereby facilitating progress in early-stage cancer treatment.
