Scanning systems that include an ultrasonic scanner, high-frequency (typically 20 and 30 MHz) miniature transducers mounted on the tip of a catheter, intravascular analysis package software, an image recorder (e.g., videocassette), and a printer. Some systems include color-flow mapping capabilities. Intravascular ultrasonic scanning systems produce 360-degree (cross-sectional) images of blood vessels for diagnostic and therapeutic applications, including the identification of arterial plaque and vessel lesions, the measurement of vessel dimensions and stenosis, the monitoring of balloon angioplasty and atherectomy procedures, and the deployment of intravascular stents.
