Abstract

Several styles of stents are being tested in human vessels. The smallest stents are made of fine stainless steel wire which is difficult to see under fluoroscopy. Visibility can be improved by either changing designs or using image processing. Some investigators use realtime processors to enhance edges and so increase stent visibility. They could obtain better results with a two-dimensional video filter which selectively enhances stents. Such a filter should not require adjustment for orientation or expansion and must operate on video with no delay. Computer studies indicate a practical algorithm to improve stent visibility is possible. While simulations indicate that with this filter normal fluoroscopy and normal subjects stainless steel coronary stents will be visible clinical studies with a working system are necessary to evaluate its usefulness. 1.
