This abstract describes the use of undersampled
cartesian and radial k-space acquisition, combined with
iterative, cost-function based image reconstruction for
rapid real-time imaging of the moving wrist. The
techniques provide sufficient image quality for
observation and quantitative measurement of changing
carpal bone angles and distances during the motion, and
spatial and temporal resolution of the image set can be
flexibly traded-off as part of reconstruction after the
k-space data has been collected. These measurements are
important for assessment of carpal bone instability,
tendon dislocation, and other pathologies of wrist joint
action.
