Background—Virtual reality techniques have recently been introduced into clinical medicine. This study examines the possibility of coronary artery fly-through using a dataset obtained by noninvasive coronary angiography with contrast-enhanced electron-beam computed tomography. Methods and Results—Ten patients were examined, and 40 to 60 transaxial tomograms (thickness, 1.5 mm; in-plane pixel dimensions,≈ 0.5× 0.5 mm) were obtained after intravenous contrast injection. The datasets were processed on a graphics workstation
