The Echographic Suction Cannula and Electronics Therefor provides a display of adipose tissue thickness for the Doctor to observe as he moves the cannula within the patient. The cannula includes a piezoelectric transducer which is pulsed by the electronics as a send pulse, to cause ultrasound to penetrate the adipose tissue and provide a reflected receive pulse. A known value fixed frequency source continuously emits cycles, and the electronics counts the cycles emitted between the send and receive pulses. This number is fed to a computer which generates bars equal in height to the thickness and moving across the CRT as the Doctor moves the cannula so he can determine regions where further Liposuction is necessary to even out the patient's appearance.
