Claim 0:
1. A method of ultrasonic inspection, comprising:
providing a pipeline inspection gage (PIG) including an ultrasonic probe within an environment including a target and a fluid such that the fluid is interposed between the target and the ultrasonic probe, the ultrasonic probe configured to transmit ultrasonic signals into the target at a first angle with respect to a surface of the target and at a first focal length;
replacing the ultrasonic probe with a phased array ultrasonic probe, the phased array ultrasonic probe configured to receive control instructions and responsive to the control instructions cause the phased array ultrasonic probe to transmit ultrasonic signals into the target at the first angle with respect to the surface of the target and at the first focal length;
generating, by the phased array ultrasonic probe at a first location of the target, a first ultrasonic beam propagating at the first angle and the first focal length specified by the control instructions;
measuring, by the phased array ultrasonic probe, one or more ultrasonic echoes resulting from reflection of the first ultrasonic beam from the target; and
outputting, by the phased array ultrasonic probe, one or more ultrasonic measurement signals representing the measured ultrasonic echoes.
