Abstract
An electronically step scanned real time ultrasonic imaging system and method is disclosed. The system includes a transducer assembly having an unequally spaced 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 co-planar, but divergent in the common plane. In the preferred embodiment, the axes of transmission diverge from one another by unequal angles, such that the tangent functions of each of the angles varies in equal increments along the array. Scan conversion techniques are used for displaying purposes, operating in the Y .theta. and Y tan .theta. formats.
