A Method for inspecting a component includes exiting a number of transducers forming an array to produce an ultrasonic transmission beam focused into the component. The array and the component are separated by a standoff. A Number of echo signals are generated using the transducers, and the echo signals are processed in a number of channels. The processing includes both dynamical focus and providing a dynamic aperture on receive, both of which compensate for refraction of the beam at the component / standoff interface. A single-turn inspection method includes:
