Abstract

Differences of opinion exist as to whether visualization of the coronary arterial tree is better with 525‐line or 1,023‐line video imaging systems. The 1,023‐line acquisition has been associated with image degradation; 525‐line display, however, has prominent raster lines that may also degrade the image. For evaluation of this issue, identical coronary arterial images were obtained with 525‐line acquisition and then displayed with either 525‐line or 1,023‐line display. The 525‐line acquisition with digital upscan 1,023‐line display had superior image quality compared with 525‐line display. With the use of 525‐line acquisition and 1,023‐line display, video images were similar to or slightly better than the identical cineangiographic images.
