Abstract
Results of preclinical experimentation using the new, high-performance ultrasonic camera system developed at the Stanford Research Institute are presented. High resolution orthographic images of in vitro and in vivo experiments demonstrate the diagnostic potential of this new technique. The in vitro studies include both transmission and reflection images of selecteed excised organs such as liver, kidney, spleen and heart. In addition, the use of contrast media as an aid in definition of the internal structures of the kidney and for comparison to radiography are shown. The in vivo results include transmission images of various anatomical structures and appendages of the human adult. Intra-abdominal images of the kidney, liver, colon, stomach and other structures obtained a relatively low sonic intensities ( lmW/cm) are presented.
