A real time 2-dimensional ultrasonic scanner for clinical use

The technical details of a real time 2-dimensional ultrasonic scanning system are described, with particular regard to the improved clinical performance over other 2-dimensional scanners. Our instrument is capable of being used with existing ultrasonic equipment extending certain standard ultrasonic machines for use as real time 2-dimensional scanners conveniently and at little cost. Initial results are given and future technical developments are discussed.
