Computerized Fluoroscopy in Real Time for Noninvasive Visualization of the Cardiovascular System

Abstract

A computerized fluoroscopic system with dedicated real-time hard-wired algorithms can be used for cardiovascular imaging with or without injection of iodine. Initial differentiated and integrated time subtraction displays are presented. Contrast studies appear adequate for visualization of cardiovascular dynamics. Cardiac images without contrast material suggest expected blood flow patterns but are difficult to interpret.
