    摘要: The invention relates to a light-emitting apparatus (100) comprising an optical waveguide, particularly an optical fiber (1), for guiding a primary light beam (Bprim) into a light-splitting unit (101) which splits it into two or more partial light beams (B1, B3, B4) which are emitted in different directions and have different optical qualities, e.g. different spectral compositions or polarizations. The apparatus may optionally comprise a detector (4) for determining a Doppler shift (Δλi) in reflected light reentering the light-splitting unit (101). This renders it possible to measure simultaneously two or more spatially independent vector components of the flow velocity of a fluid, particularly of blood, surrounding the light-splitting unit (101).

    摘要: An ultrasonic assembly suited for attachment to a catheter, e.g. for medical treatment. The ultrasonic assembly includes an adjustable ultrasonic focus mechanism arranged in connection with the ultrasonic transducer to adjust focus of ultrasonic waves generated by the transducer. The ultrasonic focus mechanism includes a fluid focus lens with at least two fluids separated by an interface such that ultrasonic waves are substantially reflected at the interface. At least two electrodes are arranged in connection with the fluid focus lens so as to allow adjustment of the interface shape, e.g. a curvature of the interface, when a voltage is applied to the electrodes. In preferred embodiments the electrodes are arranged so as to allow adjustment of the fluid focus lens in an elevation direction as well as in a radial direction. In simple embodiments with rotational symmetric geometry with the transducer positioned in the center of the fluid focus lens, ultrasonic waves can be focused in an annular ring. This is e.g. suitable for ablative or coagulative necrotic treatment of human tissue, e.g. for atrial fibrillation treatment. In some embodiments, the assembly has a number of separate individually adjustable fluid focus lens compartments allowing a more detailed control of the ultrasonic focus pattern.

    摘要: The present disclosure provides advantageous systems and methods for significantly increasing the sensitivity and selectivity for diagnostic procedures, e.g., optical biopsy. The disclosed systems and methods use a highly non-linear effect, the so-called photon avalanche. In the regime close to the avalanche threshold, small differences in density of the probe-ion under investigation or the excitation power can result in very large changes in up-conversion emission intensity. Through this effect, it becomes possible to accurately measure the signal of an optical biopsy probe-ion only in the location(s) where its concentration is highest, while at the same time significantly reducing or eliminating measurement of background signal from probe-ions distributed with a somewhat lower concentration throughout the measurement volume. Also background auto-fluorescence of the surrounding healthy tissue is essentially absent with this technique.
