1. An anatomical feature condition assessment system, comprising: an acquisition processor configured for acquiring data representing velocity and direction measurements of individual segments of an anatomical feature of a patient; a repository of mapping data associating a predetermined reference range of averaged velocity measurements and a predetermined reference range of angular direction measurements within a predetermined particular segment of said anatomical feature with a set of values indicative of medical conditions; and a data processor configured for averaging the acquired velocity and direction measurements within said predetermined particular segment of said anatomical feature and using said predetermined reference range of averaged velocity measurements and said predetermined reference range of angular direction measurements to identify a set of values associated with the averaged acquired velocity and direction measurements of the predetermined particular segment and using the identified set of values to determine a medical condition of the anatomical feature of the patient.
