Abstract
An ultrasonic probe of an embodiment includes a transmission and reception unit, a movable unit, a pressure signal detection unit, and an amplification unit. The transmission and reception unit includes a plurality of transducers, transmits transmission acoustic signals generated by the transducers, and receives reflection acoustic signals of the transmitted acoustic signals. The movable unit includes an acoustic radiation surface provided on a surface of the transmission and reception unit and moves due to a pressure applied to the acoustic radiation surface pressed against an object. The pressure signal detection unit detects a pressure signal corresponding to an amount of movement of the movable unit. The amplification unit amplifies the amount of movement of the movable unit.
Claims11
An ultrasonic probe, comprising:
- a transmission and reception unit that includes a plurality of transducers, transmits transmission acoustic signals generated by the transducers, and receives reflection acoustic signals of the transmission acoustic signals;
- a movable unit that includes an acoustic radiation surface provided on a surface of the transmission and reception unit and moves due to a pressure applied to the acoustic radiation surface pressed against an object;
- a pressure signal detection unit configured to detect a pressure signal corresponding to an amount of movement of the movable unit;
- and
- a lever unit configured to amplify the amount of movement of the movable unit;
- and
- a spring member interposed between the pressure signal detection unit and the movable unit,
- wherein the lever unit is interposed between the movable unit and the spring member, and includes an action rod, an actuation rod, and a support member.
