Abstract
Methods are provided for cardiac gating of multiple-energy projection radiographic imaging utilizing an apparatus that measures the patient's peripheral blood perfusion. The choice of methods is dependant on the patient's heart rate and the delays inherent in the imaging system. A first method allows for imaging during the diastole period of the current cardiac cycle. A second method provides an implemented delay to acquire the image during the diastole period of a subsequent cardiac cycle. The use of the apparatus that measures the patient's peripheral blood perfusion allows for an efficient and convenient means of cardiac gating while avoiding occlusion of diagnostically important anatomy.
