Biomedical Image Informatics
Abstract : The goal of biomedical image informatics is to develop techniques and systems that extract quantitative information from biomedical images and construct robust models of the structures and processes captured in the images. The word "images" is used in its broadest sense, meaning data that can be 2D, 3D or 4D in nature and changing over time. This talk will describe a number of image informatics projects conducted by the Drexel University Geometric Biomedical Computing Group. In the first project histology images of breast carcinomas are analyzed to determine if the tumor has metastasized. The second project developed techniques for automatically categorizing the memory and learning capabilities of a fruit fly model of Alzheimers Disease. This is accomplished via analysis of videos of the flies' courtship behavior. The final project generates geometric models of the individual cells of the imaginal wing disc of larval fruit flies, based on 3D reconstructions produced from confocal microscopy image stacks. Detailed geometric quantities about the cells are then computed in order to provide insight into the developmental processes that formed the wing disc.
