Abstract (en)
Disclosed is an ultrasonic probe having a transducer submerged in an acoustic transmitting liquid medium contained in a housing. The housing is formed of polymethylpentene resin having an acoustic impedance approximately equal to that of the human body. Multiple reflections and transmission loss of acoustic energy are minimized to ensure high quality tomographic images.
