ES using FET transistors for acoustothermometer

Single-channel focusable acoustothermometer for measuring the internal temperature of biological object

K. S. Drozdenko

Abstract


A new method of voltage modulation at the piezoelectric receiver output using a noise reference and electronic switch has been proposed. The functional block diagram of a focusable acoustothermometer has been developed. The specified acoustothermometer enables us to perform measurements of the internal temperature of biological object using the single-frequency single-channel method with the measurement characteristics adequate for medical applications.
