Abstract

Method of acoustical thermometry based on the registration of acoustical radiation produced by thermal motion of atoms and molecules allows mapping internal temperature field inside biological tissues. Investigations in this area are directed to the improvement of receiving methods and processing algorithms. Present paper is devoted to the investigation of one method of acoustical radiation measurement using acoustical thermograph with focused antenna. An operating laboratory prototype of acoustical thermograph is described. The results of experimentally measured receiving field of focused antenna in focal plane are presented. The possibility of localization of heated sources by means of acoustical thermograph with focused antenna has been demonstrated experimentally. This work was supported by RFBR and 6th competitive expertise of RAS young scientists.
