Title: Cortical Surface Registration and Shape Analysis
Abstract: A population analysis of human cortical morphometry is critical for insights into brain development or degeneration, which allows for investigating sulcal and gyral folding patterns. In general, such a population analysis requires both a well-established cortical correspondence and a well-defined quantification of the cortical morphometry. However, the highly folded and convoluted structures render a reliable and consistent population analysis challenging. The main focus of this talk is to develop a fully automatic pipeline and its application to a population analysis of local cortical folding changes. The proposed pipeline consists of three novel components to overcome the challenges in the population analysis: 1) automatic sulcal curve extraction for stable/reliable anatomical landmark selection, 2) group-wise registration for establishing cortical shape correspondence across a population with no template selection bias, and 3) quantitative methods of local cortical folding.
Short Biography: Ilwoo Lyu received his PhD in Computer Science in 2016 at the University of North Carolina at Chapel Hill. His research interest is mainly in developing novel algorithms for medical image analysis. His current research focuses on surface-based analysis to understand/explore highly convoluted shapes such as brain. In particular, he is working on surface registration, anatomical/geometric feature extraction/recognition, statistical shape analysis, and 3D visualization.
