ABSTRACT:
An automated angle encoder system for magnetic resonance (MRI) apparatus includes a removable encoder device placed on the orthopedic positioning device which is made entirely of nonmagnetic, nonmetallic materials and includes a glass disk which provides a GRAY output code to indicate absolute angle. The casing is made of Delrin plastic and the fiber optic cable includes nonmetallic TEFLON sheathing. Associated computer apparatus provides for an automatic input of an angle offset to provide for a neutral starting position and also for positive or negative angles of movement.
