Abstract

Abstract An ultrasonic transducer assembly includes a shaft carried by the support element of the transducer assembly. This shaft supports an array of contacts that extend circumferentially around the shaft and are spaced axially along the length of the shaft. These contacts are electrically connected to conductors which are in turn connected to an ultrasonic transducer array. The shaft of the transducer assembly is received in a receptacle that includes a reciprocating slide that can be opened to insert and remove the transducer assembly from the receptacle. The slide can be closed to lock the transducer assembly in place, and to make electrical contact with the contacts of the shaft.
