Abstract
An X-ray imaging system automatically calculates blood flow travel time by using an X-ray image acquisition system to initiate acquisition of images at a second anatomical site synchronized with introduction of contrast agent into a patient vessel at a first anatomical site. A detector automatically compares images, acquired at the second anatomical site in response to the introduction of contrast agent, with images of the second anatomical site acquired in the absence of a contrast agent, to detect when contrast agent reaches the second anatomical site via blood flow in a circulatory system of the patient. A calculator automatically calculates a blood flow travel time duration between the first and second anatomical sites based on the time elapsed between time of the introduction of contrast agent and a time the contrast agent reaches the second anatomical site in response to the detection. An output processor automatically generates a message indicating the calculated blood flow travel time.
