Ultrasonic scanning was used to assist in the diagnosis and management of ovarian tumors. Tumor response to therapy was evaluated with sequential ultrasound examinations in conjunction with clinical observations. Contact B-mode scanning and physical examination were complementary in demonstrating a change in tumor size, delineating small amounts of ascites, and identifying early omental implants. The information was used to guide the patient's management by chemotherapy.

To reduce noise- and reconstruction-related artifacts in ultrasound computed tomography, the use of combined median and Hamming-weighted spatial low-pass filtering is evaluated. The evaluation of the reconstruction filters uses both computer-generated projections of a known object with the least mean-square error criterion as well as a more subjective evaluation of conventional ultrasonic attenuation and speed of sound images.
