Abstract
In order to reduce reflection and heating of a high intensity focused ultrasound (HIFU) beam following a region of interest in tissue to which an HIFU beam was administered, at least two layers of aquasonic gel are applied at a tissue/air interface following the region of interest and the focus in a direction of propagation of the HIFU beam. A first of the two aquasonic gel layers is a foamed aquasonic gel layer, and a second of the two layers is substantially bubble-free aquasonic gel. The layer of foamed aquasonic gel is placed directly adjacent the tissue/air interface, and the layer of substantially bubble-free aquasonic gel is placed over the layer of foamed aquasonic gel, at a side thereof facing away from the tissue/air interface.
