Abstract:
1. A medical imaging system, comprising: an imaging device operable to capture two or more image data sets representative of a patient; a tracking subsystem operable to detect patient position data corresponding to each image data set and device position data corresponding to each image data set, where the patient position data is indicative of the position of the patient and the device position data is indicative of the position of the imaging device; a motion correction subsystem adapted to receive patient position data corresponding to the first and second image data set and device position data corresponding to the first and second image data set, and the motion correction subsystem is operable to detect a change in relative position between the patient and the imaging device; and an image subtraction subsystem adapted to receive at least a first image data set and a second image data set from the imaging device, the image subtraction subsystem is operable to perform a digital subtraction operation between the first image data set and the second image data set when no substantial change occurs in the relative position between the patient and the imaging device.
