Abstract
The invention disclosed herein features a photoacoustic scan head that includes laser fibers integrated into the housing of an arrayed ultrasound transducer using an optically transparent epoxy or other resin. The light-emitting ends of the fibers are positioned adjacent to the front surface of the transducer and direct laser light onto a subject being scanned by the transducer. The light beams generated by the fibers may be angled to intersect the acoustic field generated by the transducer so as to generate a photoacoustic effect in the region scanned by the transducer.
