    摘要: In one aspect, matching layers for an ultrasonic transducer stack having a matching layer comprising a matrix material loaded with a plurality of micron-sized and nano-sized particles. In another aspect, the matrix material is loaded with a plurality of heavy and light particles. In another aspect, an ultrasound transducer stack comprises a piezoelectric layer and at least one matching layer. In one aspect, the matching layer comprises a composite material comprising a matrix material loaded with a plurality of micron-sized and nano-sized particles. In a further aspect, the composite material can also comprise a matrix material loaded with a plurality of heavy and light particles. In a further aspect, a matching layer can also comprise cyanoacrylate.

    摘要: 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.
