Abstract
A method and apparatus for allowing determination of patient position change relative to an imaging device and/or allowing digital subtraction in an operative position. The system can include devices for determining a position of a patient at various times and comparing the various positions of the patient. Further, a digital subtraction may be performed if the patient change is not above a threshold value and/or if motion correction can occur.
