ABSTRACT:
An improved ultrasonic scanning head is disclosed for use in an apparatus for imaging sections of a body by transmitting ultrasonic energy into the body and determining the characteristics of the ultrasonic energy reflected therefrom. The scanning head includes a scanning window which comprises an acoustic lens for converging the scan of the ultrasound beam. This serves to reduce geometrical distortion.
