Computerized ultrasound tomography of the human head: experimental results.

Computed ultrasound tomograms of infant and adult human cadaver heads are presented and compared to x-ray CT scans obtained in the same horizontal planes. The images were reconstructed from broadband pulsed transmission data obtained using the rotate-translate scan mode. A formalin-fixed infant cadaver head was scanned using a 5 MHz center frequency yielding a transkull attenuation reconstruction which displays enough anatomical detail to warrant continued work on the method with the hope of eventual clinical application.
