“…A periodic structure, such as the rib cage, generates diffraction patterns that persist well beyond the plane of focus. This effect, first described by Talbot (23), has been analyzed in some detail by Korpel (24). These diffractive effects already have been reduced to some extent by increasing the ultrasonic bandwidth of the camera to about 40% and a further increase in bandwidth could be beneficial.…”

Results are described of in vitro biological experimentation using a new through-transmission ultrasonic camera system developed at the Stanford Research Institute. The camera system produces real-time focused, orthographic images of a 15 times 15 cm field. The in vitro studies, which demonstrate the diagnostic potential of the new technique, include transmission images of selected excised organs such as liver, kidney, spleen, and uterus. In addition, preliminary studies evaluating ultrasonic image quality and the effect of out-of-focus structures are discussed.

“…This finding led us t o increase the insonification bandwidth, resulting in a partial suppression of this disturbance. The problems of transmission imaging are now receiving increased attention in the literature and several possible directions for future research have been suggested (8,13,14). Further studies of the diffractive and refractive phenomenon that occur in transmission imaging are under way in our laboratory and we hope to deal effectively with these sources of noise in the future.…”

A new transmission ultrasound camera system has provided focused images in real time through the abdomen of adult volunteers at average incident sound intensity levels of less than 1 mW/cm-2. The camera uses a unique acousto-mechanical lens/deflection system and a linear array of piezoelectric transducers to detect the ultrasound image. BONY STRUCTURES AND COSTAL CARTILAGES WERE CLEARLY SEEN. The colon was regularly seen and the kidney could be outlined in several subjects. The stomach and duodenal bulb were demonstrated and peristalsis was observed using a barium contrast material. The camera has the potential of extending the use of ultrasound in clinical medicine by providing an ultrasound soft tissue imaging system analogous to an x-ray fluoroscope. The need for further clinical evaluation and research to improve the images is emphasized.
