CS Seminar: Zongwei Zhou

Description

Zongwei Zhou, an incoming assistant research professor in the Department of Computer Science at the Johns Hopkins University and a member of the Malone Center for Engineering in Healthcare, will give a talk titled "Early Cancer Detection by Computed Tomography and Artificial Intelligence" for the Department of Computer Science.

Abstract

Cancer, a leading cause of death, can be effectively treated if detected in its early stages. However, early detection is difficult for both humans and computers. AI can identify details beyond human perception, delineate anatomical structures, and localize abnormalities in medical images, but achieving this level of reliability requires "AI-ready" datasets—big datasets with carefully prepared annotations—and resources that are often limited and expensive in medical imaging. Several disciplines—particularly the success of GPTs—have shown the transformative power of scaling laws for AI advancement, but this concept remains relatively under-explored in medical imaging. This talk will discuss how scaling AI-ready datasets can positively impact new methodologies and applications in medical imaging, with a special focus on enabling earlier cancer detection.
