Abstract

Ultrasonic images of cadaver arteries are presented in this paper. The images were produced from within the arteries by a pulsed transducer capable of being mounted on a 0.8 mm catheter equipped with both a guide wire and a laser delivery system. The image data were acquired, processed, and displayed by a computer based real-time system. Example images show some of the display formats which are available for elucidating the internal structure of arteries with this imaging modality. Transverse and radial sections of the artery are shown in both A-Scan and B-Scan modes. Derived thickness images are also presented. In each mode the internal artery structure, including plaque areas, is clearly apparent. Histologic sections are shown beside ultrasonic data to verify the utility of these images.
