Mondino I.R.C.C.S., 6Department of Molecular Medicine - Unit of Pathology, University of Pavia, Foundation IRCCS Policlinico San Matteo The development of new ultrasound (US) probes based on Capacitive Micromachined Ultrasonic Transducer (CMUT) technology requires an early realistic assessment of imaging capabilities. We describe a repeatable experimental protocol for US image acquisition and comparison with magnetic resonance images, using an ex vivo bovine brain as an imaging target.
