1. An industrial inspection device comprising:
an ultrasonic phased array having ultrasonic elements;
a drive circuit connected to the ultrasonic elements to transmit an acoustic wave;
a receive circuit for receiving signals from acoustic reflections, the circuit having receive channels that are electrically connected to a subset of the ultrasonic elements that substantially spans a width of those transmit ultrasonic elements; and
a memory for storing the received signals,
wherein a width of the elements used to receive is at least 90% as wide as the elements used to transmit.
