Abstract

This paper describes experimental results of tests performed on cadaver arteries using a pulsed ultrasonic imaging transducer. Computer generated three-dimensional hidden line images based on pulsed data show the artery thickness both in normal areas and in areas with complex plaque. Thin fatty deposits on the interior artery wall are also imaged. A series of ultrasonic echo images were taken on human aorta plaque deposits and the corresponding set of histological sections prepared. A side-by-side presentation is made in which specific plaque features and internal structures are identified ultrasonically and verified on the histological section. The performance of the ultrasonic transducer is consistent with an ability to perform ultrasonic signature arterial tissue typing. The transducer is sized to allow mounting within a 0.8 mm catheter that is equipped with a guide wire and a laser delivery system.
