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.

Ultrasonic compound scans from brain specimens.

This paper demonstrates the high quality of ultrasonograms obtained from brain specimens by compound scanning when the angular range of insonation is extended to 360 degrees. The technique employs linear photographic superposition and a commercial real time scanner as basic instrument. Comparative anatomical cross-sections showed that the major normal structures and pathological processes like hemorrhage, tumors, infarctions and edema are displayed. The image quality indicates the potential of this approach when applied to organs accessible to this type of scanning procedure.
