ABSTRACT
We propose a new approach for quantifying regions of
interest (ROIs) in medical image data. Rotationally invariant
shape descriptors (ISDs) were applied to 3D brain regions
extracted from MRI scans of 5 Parkinson's patients and 10
control subjects. We concentrated on the thalamus and the
caudate nucleus since prior studies have suggested they are
