Abstract
Phased arrays serve the same purpose as multi-element switched arrays, and that is electronical fast scanning, with ultrasound.
There is, however, a fundamental difference between the two systems.
The first case is based on the principle of beam-steering, whereas in the latter beam-position is varied by activating several transducers sequentially.
