Abstract
Systems and methods of ultrasound imaging of an object that includes multiple depth zones. Each of the zones can be imaged using a different frequency, or the same frequency as another zone. A method includes imaging a first zone using plane wave imaging, imaging a second zone using tissue harmonic imaging, and imaging a third zone using fundamental and subharmonic deep imaging. The depth of each zone can vary based on the ultrasonic array, and correspondingly, the F # used for imaging the zone. In an example, zones can be imaged at different F #'s, for example, at F #1 for the first zone, at F #2, F #3, or F #6 for one or more zones that extend deeper into the object than the first zone. The method can also include forming an image based on the received signals from the multiple zones, and blending the transitions between the zones.
