Methods and system for producing combined photoacoustic/ultrasonic image frames use a low-power narrow beam laser to direct sequential pulses along a path overlying an internal region of interest. Photoacoustic responses are received and used to generate sub-frames. Between each of the laser pulses a plurality of ultrasound pulse-echo beams are sequentially emitted towards the region of interest, and the reflections are received and used to generate ultrasound sub-frames. The photoacoustic sub-frames are combined to produce a photoacoustic frame, and the ultrasound sub-frames are combined to produce an ultrasound frame. The photoacoustic and ultrasound frames are combined to produce an image frame. The method and system are suitable for producing real-time, high-contrast video.

Real-time photoacoustic and ultrasound imaging system and method

A method and apparatus for testing a composite structure. A pulsed laser beam having a number of properties is generated. Each of the number of properties is within a selected range. The pulsed laser beam generated by the generation laser system is directed towards a composite structure comprised of a number of composite materials. A number of ultrasonic waves are formed in the composite structure when the pulsed laser beam contacts the composite structure without causing any undesired inconsistencies in the composite structure outside of selected tolerances.
