Abstract
A static switching scheme along transducer elevation for obtaining beam line from multiple firings. Between firings for an associated beam line the elevation aperture is changed depending upon the image plane focus depth. For a single image plane focus beyond a deepest break point, a widest elevation aperture is used during one firing. During other firings for the beam line the elevation aperture is narrowed. Each of multiple break points separate a distinct depth region. Echo data for a beam line includes echo data from one firing for one region and from another firing for another region. Echo data from multiple firings is blended in vicinity of region boundaries. For multiple image plane foci applications, the elevation aperture for a given firing is determined by the target image plane focus for such firing.
