Background, Motivation and Objective Our 3D ultrasound computer tomography (3D USCT) system aims at high-resolution images for early breast cancer detection. The current system consists of 2041 ultrasound transducers. Positioned on a semi-ellipsoid, the quality of the produced images is highly sensitive to the system calibration. Parameters for calibration are: the position of ultrasound transducers, temperature distribution in the medium and the electronics’ system response. A calibration accuracy better than one quarter of the wavelength is targeted for optimal image quality.
