Abstract
An ultrasonic imaging apparatus for operation in either or both linear and sector scan modes is disclosed which employs a common array of transducers. Circuitry is provided for controlling the order and timing of pulse echo transmission and reception, which further include control circuitry to operate variable delay and switching circuitry to generate transmission signals to be applied to the transducers, and to direct echo signals received by the transducers for processing to provide the image of the structures being inspected. Suitable interconnection/switching circuitry is provided so as to minimize prior art requirements for use of different elements for the separate scanning modes, with concomitant expenses associated with the larger number of components being reduced.
