Sandy Napel is a Professor of Radiology (and of Medical Informatics and Electrical Engineering, by courtesy) and Co-Director of the 3D Medical Imaging Laboratory.

Dr. Napel's primary interests are in developing diagnostic and therapy-planning applications and strategies for the acquisition and visualization of multi-dimensional medical imaging data. Examples are: creation of three-dimensional images of blood vessels using CT, visualization of complex flow within blood vessels using MR, computer-aided detection and characterization of lesions (e.g., colonic polyps, pulmonary nodules) from cross-sectional image data, visualization and automated assessment of 4D ultrasound data, and fusion of images acquired using different modalities (e.g., CT and MR).
