ULTRASONIC WAVEGUIDE Russian patent published in 2012 - IPC B06B3/00 A61B8/00 G01N29/24 

FIELD: physics.

SUBSTANCE: invention relates to ultrasonic devices and can be used in a medical therapeutic or diagnostic system. Disclosed is an ultrasonic device, having an ultrasonic waveguide, an ultrasonic transducer lying at one end of said ultrasonic waveguide and an ultrasonic receiver lying on the other end of said ultrasonic waveguide for receiving said ultrasonic wave. The ultrasonic waveguide has at least one electroconductive section having a first acoustic impedance Z₁ and at least one electrically insulating section having a second acoustic impedance Z₂. The electroconductive section is acoustically coupled with the electrically insulating section. The electroconductive and electrically insulating sections are assembled alternately.

EFFECT: high accuracy of diagnosis owing to use of a waveguide in magnetic-resonance medium conditions.
