Optimal display of the coronary arterial tree with an upscan 1,023-line video display system.
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.
