| Abstract | Currently, echo is widely used as a ultrasound tomography method. Another tomography method, USCT (Ultrasound Computed Tomography) uses reflected wave as well as transmitted wave, which can construct the map of medium sound speed distribution. Greenleaf et al.1 showed sound speed and attenuation index could be used to distinguish benign masses from cancer by measuring the sound property of breast. However, this method did not result in clinical test due to the limited performance of CPU in those days. Duric et al.2 developed the Computed Ultrasound Risk Evaluation (CURE) system with the clinical goals of whole breast. In this system, the ring-shaped transducer (Fig.1) surrounding the breast moves vertically to construct tomographic images. USCT can construct three different images, reflection image, sound speed image and attenuation image with each data collection. |
