Abstract
An automated method and improved device provide a measurement of blood flow through the heart by the detection and analysis of radioactivity emitted by a radioactive tracer introduced into a patient's bloodstream. Real time, cardiac cycle by cardiac cycle information is processed and displayed to provide diagnostically useful information on an essentially ongoing basis as the patient is being tested.
