1. A method for synchronizing the acquisition of images of an X-ray system with the cardiac cycle of a patient to aid in X-ray imaging of a patient, said method including the steps of: monitoring the patient's cardiac cycle for a first cardiac trigger; imaging the patient in response to said first cardiac trigger to form an X-ray image; monitoring the patient's cardiac cycle for a second cardiac trigger; recording an offset image; and combining the X-ray image and the offset to determine an improved X-ray image of the patient.
