ABSTRACT:
A mechanical scan type ultrasound scanner head for ultrasound examination systems, which is capable of detecting the position or distance of movement of an ultrasound transducer in mechanical scanning operations, and which includes: an ultrasound scanner head assembly movable along a subject to be scanned; an ultrasound transducer element mounted on the ultrasound scanner head assembly to transmit and receive ultrasound signals at predetermined intervals in travel distance along the subject; a rotary tracking member mounted on the scanner head assembly in the proximity of the ultrasound transducer element and rotatable at a rate commensurate with the distance of movement of the ultrasound transducer element; and a position measuring means connected to the rotary tracking member to measure the distance of travel of the ultrasound transducer element from an initial position of a scanning operation by way of a rotational angle of the rotary tracking member.
