Abstract

A new transmission ultrasound CT breast scanner (Techniscan Medical Systems, Inc.) was installed for pre-clinical testing at UCSD Medical Center. The scanner utilizes a 3D inverse scattering method to produce whole-breast tomographic images with resolution approximately 1.5 mm in plane, 3.5 mm slice profile and slice spacing of 1 mm. Sound speed accuracy and sensitivity were found to be highly linear (R2=0.99) over the wide range of 1370–1620 m/sec. Attenuation provided a wide image contrast and is able to localize and identify breast lesions. We present representative cases of human subjects enrolled in the pre-clinical study and describe future plans for the system.
