On the basis of our own 20-year experience of research and development, there are discussed advances and prospects of creation and use of technical means for cryosurgery, including different ultrasonic units for:
1. Control of cryolesion and next tissue regeneration;
2. Monitoring of depth of frozen zones formed by cryoapplicators with built-in ultrasonic transducers;
3. Monitoring of acoustic, thermal and mechanical contacts between cryoapplicator and tissue during freezing;
4. Combined use of cooling (without ice formation) and ultrasound in physiotherapy; and
There are discussed also the possibilities of using cryosurgery with next ultrasonic
hyperthermia, some actual problems of automation of freezing procedure, and other
challenging applications of ultrasound in cryomedicine.
