Abstract
Abstract
Cryosurgery is a surgical method of biological tissue removal at extremely low temperatures. One of the main issues of cryosurgery is low accuracy in determining the boundaries and depth of frozen tissue. This paper presents the results of the development of a sounding pulse generator for evaluation of the electrical characteristics of biological objects during cryodestruction. The developed sounding pulse generator is a part of the experimental system for the development of a tomograph, using the principle of electric impedance tomography. This paper presents an experimental prototype of the sounding pulse generator applied to study the impedance properties of biological tissue in a wide temperature range from minus 196°C to plus 50°C. The application field for the developed generator: medical systems for visualization of boundaries and depth of biological tissue freezing during cryosurgical operations.
