Background, Motivation and Objective 3D Ultrasound Computer Tomography (3D USCT) promises reproducible high-resolution images for early detection of breast tumors. Our prototype provides three different modalities: reflectivity, speed of sound, and attenuation. For reflectivity reconstruction a 3D synthetic aperture focusing technique (SAFT) is used which calculates one reflectivity value for each voxel from about 10 million A-scans. Due to this averaging the directional information of the reflection is lost. The aim of this work was to generate directional reflection characteristics for each voxel in the volume and to evaluate the results.
