Web8 de out. de 2003 · Results are presented for a new formulation of HIFU phantom material made with polyacrylamide gel and bovine serum albumin. This formulation closely matches the acoustic attenuation as well as the velocity and impedance of tissue, while providing a uniform and optically transparent medium. The phantom material turns permanently … WebA HIFU transducer (MEDSONIC LTD, Limassol, Cyprus), with an operating frequency of 4.4 MHz, was used to sonicate an agar-based phantom. The phantom included 6% w/v agar and 4% w/v silicon dioxide. A 3D-printed (F270, Stratasys Ltd., Minnesota, USA) experimental setup was used to hold the transducer and the phantom stable at fixed … daylight day club
