Paper Abstract

Recent advances in catheter-based ultrasound imaging technology have led to the clinical reality of imaging coronary arteries and other vasculature in a manner that was not possible in the past. For the first time dynamic cross-sectional views of blood vessels can be obtained in patients in real time. Currently available instruments include catheters that contain a mechanically rotating ultrasound probe, catheters in which the ultrasound crystal is fixed but a rotating mirror transmits and receives ultrasound in a circumferential format and catheters with synthetic aperture array processing. Considerable amount of in vitro work has given a fundamental basis for interpreting intravascular ultrasound images and for using the technique in a quantitative manner to assess vascular anatomy. The feasibility studies, the current cited clinical applications and the areas where further work is required are reviewed.
