ABSTRACT:
An ultrasonic transducer is disclosed comprising a transducer head assembly containing a movable crystal holder containing a crystal which is coupled to a stationary base by mechanical linkage means. A motor adapted to provide linear reciprocating motion is coupled to the mechanical linkage means for causing the crystal holder and crystal, when driven by the motor, to undergo reciprocating swinging motion for transmitting ultrasonic energy to and receiving echo signals from an object in front of the transducer in a sector scanning manner.
