New technologies and methods designed to reduce the risk and magnitude of surgical manipulations are being actively introduced into clinical practice, one of which is the method of high-intensity focused ultrasound (HIFU) thermoablation. However, it is quite difficult to assess the spatial distribution of acoustic and thermal fields when selecting a therapy scheme. To simulate the architectonics of the treatment area it is proposed to use a dosimetric phantom. The pattern of changes in the phantom in the heat-affected zone is shown with an ultrasound scanner in real time, which allows to visualize structural changes in the area of thermal destruction and verify the dosimetric plan of ultrasound therapy.
