  • Ultrasonic diagnosing apparatus with steerable ultrasonic beams
    Patent number: 5105813
    Abstract: A convex probe with N ultrasonic transducers placed in a row of predetermined curvature. Each of transducers is connected, via an array of switches, to an ultrasonic transmission/reception driver. Each of the driver forces a transducer to transmit or to receive ultrasonic beams. In addition, the drivers generate electrical signals corresponding to ultrasonic beams received at the transducers. All electrical signals from the drivers are added, and then manipulated to generate sets of data, which in turn are collected to produce a one-frame image to be displayed.
