Abstract
A probe for use in an ultrasonic diagnostic apparatus in which the acoustic impedance of a liquid medium put between the oscillator and the living body is made equal to that of the casing having the medium sealed therein, by using a low molecular weight polymer product of chlorotrifluoroethylene as the liquid medium. This can suppress the multi-reflection echoes within the casing to thereby improve the quality of the tomographic images obtained by the apparatus.
