description: This work is devoted to testing the calibration method of the ultrasonic thermometry method for the biological tissue model.
The experimental part was carried out on the basis of a diagnostic module, which is part of the medical device for therapy with focused ultrasound Dater, developed by SPbPU and JSC Novosibirsk Instrument-Making Plant.
 During the study, an experimental setup was assembled for calibration by the method of uniform external heating, a calibration procedure was worked out, the coefficient of thermal deformation of the ultrasonic signal K = 590 Â± 40 Â° C for the fabricated tissue-equivalent material was determined.
The results showed that the developed technique is recommended for use to determine the coefficient of temperature deformation of the ultrasound signal for biological tissue. The developed two-dimensional numerical models for cooling tissue-equivalent material showed close to the experiment the unevenness of the temperature field in the window for recording ultrasonic data, but the overestimated cooling time of a sample of tissue-equivalent material.
