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.
