Total displacement variations in computed bead position from 0 mm, 2 mm, and 5 mm
randomly applied displacement offsets to initial bead positions which simulate CT/MR
registration errors. These induced offsets resulted in less than a 10% change in the overall
data-model match. A good correspondence is achieved when the distance between measured
displacement (X) and predicted displacement (O) is small (i.e., line connecting (X) and (O)
at each point is small).
