Colloquium Series: Dr. Ge Wang

November 11 @ 3:30 pm - 4:30 pm

Title: Modern CT Theory: Insight and Beyond

Speaker: Ge Wang, https://faculty.rpi.edu/ge-wang

Abstract: Over the past century, computed tomography (CT) has experienced rapid advancements, grounded in integral geometry, linear algebra, and numerical optimization, each marked by sophisticated mathematical nuances. Today, CT is the most widely used medical imaging modality, with approximately 300 million scans performed annually worldwide for screening, diagnosis, and therapeutic guidance across a broad spectrum of diseases. In this talk, I will provide a heuristic overview of CT theory, spanning from classical Fourier slice theorems to modern algorithms for cone-beam spiral CT image reconstruction. Then, I will delve into cutting-edge topics such as interior tomography, robot-based CT, and stationary CT, with an emphasis on generative AI-based image reconstruction.
