FAAST-PA is a Phased Array instrument (PAUT) which is much more powerful than any conventional phased array electronic.
Thanks to its sinusoidal pulser and its real time data processing software, the FAAST has the capability to transmit multiple sound beams, multi-oriented and/or multi-focused, using multi-element probes with only one single shot, and then to process signals received from all beams in real time.
