    摘要: In accordance with embodiments of the present technique, a combined modality imaging system includes a first imaging device of a first modality and a second imaging device of a second modality that is different from the first modality. The first and the second imaging devices are both adapted to interact with a contrast agent adapted to be received in a subject. The contrast agent includes an deformable particle that has a geometry that varies in response to an emission from the first imaging device. The deformable particle also includes a fluorescent component adapted to emit electromagnetic radiation that is detectable by the second imaging device and a quenching component separated from the fluorescent component at a distance based on the geometry and that which is adapted to absorb a portion of the electromagnetic radiation from the fluorescent component.

    摘要: The present invention provides a compact optical probe assembly that measures ultrasound in materials. The probe uses angle-terminated optical fiber to direct illumination laser light at the surface of a remote target. Ultrasonic displacements at the surface scatter the illumination laser light. Angle-terminated optical fibers collect phase modulated light and direct the phase modulated light to an optical processor to produce a signal representative of the ultrasonic surface displacements. The probe may also incorporate angle-terminated optical fibers to direct generation laser light to the surface of a remote target to generate ultrasonic surface displacements. Optional shared beam forming element(s) may optically act on the illumination laser and collected phase modulated light.
