Abstract
An ultrasound diagnostic apparatus and a probe therefor for a body cavity of a patient are disclosed. The probe comprises a transducer which rotates to obtain sectional ultrasound images along various angles. The apparatus comprises a means for indicating the rotation angle of the transducer. A mark for indicating the angle is provided on a surface of the transducer. The rotation angle is detected electrically to be displayed on a CRT screen. For more precise detection, slack removers for removing slacks of rotation wires are provided. A rotation angle indicator for indicating the rotation angle of a rotation knob which represents the rotation angle of the transducer is provided on the operation portion.
