Abstract:
1. A method for subtraction of re-projection data in medical diagnostic imaging, the method comprising: acquiring C-arm x-ray data in frames representing a left ventricle of a patient projected to different planes, the frames acquired at different times; constructing, with a processor, the C-arm x-ray data into volume data representing a volume of the patient, the volume of the patient including the left ventricle; masking, with the processor, the left ventricle from the volume data; projecting, with the processor, the volume data without the left ventricle to one of the planes corresponding to one of the frames; subtracting, with the processor, the projected volume data from the C-arm x-ray data of the one frame; and generating an image of the left ventricle as a function of a result of the subtracting.
