Abstract :
At KIT we are developing a 3D Ultrasound Computer Tomograph (USCT) for breast cancer detection. Our current reconstruction algorithm, Synthetic Aperture Focussing Technique (SAFT) assumes single scattering for the reconstruction of 3D images from the measured data. Higher order reflections cause artefacts in the reconstruction.
