description: The subject of the graduate qualification work is âDiagnostic functions of a power piezoelectric transducer in devices for HIFU therapyâ. The given work is devoted to the creation of an experimental facility which allow to use of a power piezoelectric transducer for therapy and diagnostics of a biological object. The system is able to perform thermal ablation, form a short probe signal, and also register an echo signal. Estimate of the degree of exposure to HIFU radiation consisted in the analysis of echogenicity and deformation of the object by acoustic radiation force impulse. As a result, it was possible to register changes in the biological object after thermal ablation. In addition, it is possible to control the temperature and check the presence of the working fluid with a power transducer. In addition, it is possible to control the temperature and check the presence of the working fluid with a power transducer. Control is carried out by measuring the modulus and phase of the impedance of the transducer. The work is aimed at improving the HIFU-therapy complexes developed by the Laboratories of ultrasonic technologies.
