Ultrasound Computer Tomography (USCT) is used to map local wave propagation parameters, such as speed of sound, as potential imaging biomarkers. A reflector-based reconstruction algorithm using a conventional transducer was proposed in [1], yielding satisfactory reconstructions thanks to dynamic-programing based reflector delineation and angular-weighted totalvariation regularization. In this work, we demonstrate an extension to a 2D array transducer case, where 3D reconstructions are facilitated by additional information from multiple overlapping transmits-receives wave-paths that traverse the medium. We aim to model an existing transducer and study reconstruction feasibility and resolution via numerical simulations.
