US Patent 7502641 Method for imaging the relative motion of skeletal segments

Methods and apparatus for measuring the movement of bones during joint motion in a subject using a motion table, an imaging device, and software program for tracking, calculating and graphing the results of the motion study. The apparatus is a motion table used to control the movement of the subject while an imaging device captures images during that movement. The images are analyzed using a computer software program that tracks the individual bones that make up the joint, calculates their relative movements, and graphically displays the results as a function of time.
