Ultrasonic scanning apparatus and techniques.

摘要

There is disclosed an ultrasonic scanning apparatus for directing ultrasonic energy towards a body under investigation, such as the body of a person. The scanning apparatus consists of a focussed ultrasonic transducer which is capable of radiating a beam of ultrasonic energy in a given direction. The beam emanating from the transducer impinges upon at least one surface of a rotating reflector where the rotating reflector directs the beam relatively perpendicular to the direction of the beam as propagated from the transducer. The redirected beam can then be further focussed or reflected to further shape the beam prior to directing the beam towards the body under investigation.
