Abstract
An electronically step scanned real time ultrasonic imaging system and method is disclosed. The system includes a transducer assembly having an array of elements, each with an axis of transmission along which it transmits its main ultrasonic energy when electrically stimulated. The elements are disposed in a curvilinear array, wherein their axes of transmission are approximately coplanar, but divergent in the common plane. This configuration provides a relatively large scanned area without need for either electronic or mechanical sector scanning techniques to steer the incident ultrasonic energy over a large angle.
