Paper Abstract

The placement of multiple coronary stents requires fine judgments of distance between a deployed stent and stent/guidewire assembly. The goal of this deployment is to achieve continuous and gapless coverage between them. However, making these judgments is difficult because of limited system resolution, noise, relatively low contrast of the deployed stent, and stent motion during the cardiac cycle. In this work, we extend our previous work by investigating wider range of conditions associated with this task. The present studies consider number of frames and frame rate separately, and include stabilization of the stents as a way to quantify the performance effects of stent motion. We find that (1) stabilization reduces the uncertainty when detecting the gap size; (2) observer performance increases with the number of frames; (3) the effect of display frame rate is highly dependent on the motion of the target.
