Patent ID: 7697974

Claim:
A method utilizing a computer in communication with an imaging system and a monitoring system for analyzing stored frames of time-stamped imaging data and time-stamped physiologic data obtained during a study of a patient during a plurality of cardiac cycles, the imaging data comprising frames representative of a succession of images of the patient's heart, said method comprising: time-stamping each of the frames of the imaging data acquired by said computer using a first clock within the imaging system; time-stamping at least one feature within the physiologic data using a second clock within the monitoring system, the second clock different than the first clock; storing the time-stamped frames of the imaging data and the time-stamped physiologic data within a memory device; synchronizing time-stamps generated by the first clock with time-stamps generated by the second clock by comparing the first clock and the second clock to a reference clock within the memory device; analyzing the stored time-stamped physiologic data to determine times of a selected phase in the plurality of cardiac cycles; selecting, in the plurality of cardiac cycles, the stored time-stamped frames of imaging data corresponding to the determined times of the selected phase; aligning and averaging the selected frames of imaging data corresponding to the selected phase across the plurality of cardiac cycles; and producing a single representative frame of image data based on the aligned and averaged frames of imaging data.
