Abstract

A prototype 2-D cylindrical section phased array, as part of an adaptive hyperthermia system, was used to examine the role of implantable acoustic sensors for phase aberration correction and motion compensation in ultrasound hyperthermia. After phase aberration correction and motion compensation, enhanced focal patterns were achieved even in the presence of significant aberration and motion. The limited number of acoustic sensors implanted inside a tumor in the clinic necessitate phase aberrations measured at one point to be extrapolated to other neighboring focal points. According to the results obtained here, significantly improved focal patterns can be obtained if phase aberrations and beam shifts are mainly caused by aberrators close to the array surface and extrapolated focal points are close to measured points.
