ABSTRACT:
A multi-plane electronic scan ultrasound probe having a rotary member rotatably mounted on a distal end portion of an elongated catheter member of the probe and support thereon an ultrasound transducer consisting of a row of a large number of ultrasound elements. The rotary member is connected to a rotation control knob on a manipulating head of the probe by way of rotation transmission wires extended through the catheter member and via a drive pulley mounted on the manipulating head in association with the rotation control knob to turn the ultrasound transducer through an arbitrary angle in multi-plane electronic scanning by manipulation of the rotation control knob. In addition, for the purpose of tilting the ultrasound transducer through a desired angle, the ultrasound probe is provided with a tilting mechanism to tilt the rotational axis of the rotary member in a predetermined direction, including a tiltable support for the rotary member, a tilt control means provided on the manipulating head, and a tilt signal transmission means for transmitting a tilt control signal from the tilt control means to the tiltable support.
