TOPIC

A Geometric Approach to Brain Imaging

Abstract:

Brains differ in size, shape, and function. However, population analyses of brain images have been usually performed following a spatial normalization step. This is the process of deforming the individuals' brain scans to a common template image. Therefore, size and shape are usually treated as nuisance variables. In this talk, I will introduce a comprehensive framework for the analysis of images whose domain is subject to variability from sample to sample. The proposed framework enables a joint representation of the geometric and functional aspects of the data. We apply the proposed model to the analysis of imaging data of cortical thickness, acquired from the brains of different subjects, and thus lying on domains with different geometries.
