ABSTRACT:
Systems and methods to obtain an ultrasonic image of a large detection area are disclosed. A system includes a source of ultrasound generating ultrasonic energy and projecting the ultrasonic energy from a projecting end and an adapter interfaced to the projecting end and ultrasonically coupling the source of ultrasound to a first surface of the structure to be imaged at an adjustable angle of incidence. A method includes ultrasonically coupling a source of ultrasonic energy to a first surface of a structure to be imaged with an adapter, the adapter adjustable to a select a first angle of incidence and a second angle of incidence, projecting ultrasonic energy into the structure, and detecting a reflected acoustic energy from the structure with an ultrasound camera. A first angle of incidence is selected to introduce a longitudinal wave into the structure, and a second angle of incidence is selected to introduce a shear wave into the structure.
