Morphometry and Motion Analysis

Recent News

Article on using Principal Component Analysis for modeling carpal bone displacement during wrist maneuvers is now published in the Journal of Biomechanics

Brief description

Tracking of the motion of the carpal bones during an active maneuver. Video is here.

Our research group is investigating techniques to quantify morphometric characteristics and motion of tissues employing in vivo imaging. The goals are two fold: (1) to allow a comparison across populations based on sex, age and other factors, in the context of disease, and (2) to allow the measurement of changes in tissue shape in conditions where such changes may occur because of the disease process or due to intervention. Applications include wrist instability, osteoarthritis, and neurodegenerative disorders.
