Ultrasound internal examination system

摘要

Described herein is an ultrasound internal examination system which essentially includes an ultrasound probe having a rotatable ultrasound transducer element mounted at the tip end of a flexible cable for movement in radial and linear directions, an operating unit having remote control means for the ultrasound transducer element, including a rotating means, a linearly reciprocating means, a rotational angle sensor means, and a linear position sensor means, and a signal processing means adapted to produce at least an ultrasound tomographic image of radial scan direction or an ultrasound tomographic image of linear scan direction on the basis of ultrasound echo signals from the ultrasound transducer element and signals from the rotational angle sensor means and the linear position sensor means, and arranged to display at least one of the ultrasound tomographic images of radial and linear scan directions along with a marker indicating the linear position or angular direction of the ultrasound transducer element in the other scan direction.
