Ultrasonic rotational compound scans of the breast.
The ultrasonic rotational compound method using a conventional real-time linear-array scanner and linear photographic superposition has been applied in vivo to the mammary gland. Scanning apparatus and imaging procedure are described. Before scanning, the sound velocity of the tissue has to be determined individually. A method of matching the sound velocity of the immersion bath to that of the tissue is described. The image quality obtainable with this relatively simple technique is comparable to that of most sophisticated scanners.
