    摘要: Optical probes are provided for miniature applications, e.g. medical inspections and procedures or in industrial inspections. The probe comprises an optical guide, a first lens system mounted on a distal end portion of the optical guide for focusing light from the optical guide, an actuator for displacing the distal end portion and the first lens system to enable optical scanning, and a second lens system fixed inside the probe to receive radiation from the first lens system. The second lens system is selected to enable a deflection of radiation from the first lens system in a direction corresponding to a direction of displacement of the first lens system by the actuator. The second lens system can be a cheap negative lens, and the invention is thereby particularly useful for increasing the field of view (FOV) of cheap, disposable optical probes.

    摘要: The present invention relates to an apparatus 100 and, a method and a computer program for determining a parameter indicative of a tissue type of an associated tissue 116. In particular, the invention relates to an apparatus 100 comprising a spectrometer 102, which spectrometer comprises a light source 104 and a detector 106, 108 arranged to measure an optical spectrum. This enables determination of a first parameter being indicative of a bile concentration. As the inventors of the present invention have made the insight that bile concentration may serve as a discriminative feature for different tissue types, the apparatus is arranged to determine a second parameter indicative of a tissue type based on a concentration of bile. According to a specific embodiment, the apparatus further comprises an interventional device 112.

    摘要: The present invention relates to an apparatus, a method and a computer program for determining a lipid-water ratio and a scattering parameter of a sample. In particular, the invention relates to an apparatus comprising a light source and a detector arranged to measure an optical parameter at various wavelengths, where the wavelengths are selected so that at two of the wavelengths the absorption coefficients for both water and lipids are substantially identical. This enables determination of a scattering parameter. A further measurement at a third wavelength enables determination of a water-lipid ratio. According to a specific embodiment, the light source and the detector are arranged in relation to an interventional device, so as to be able to examine a tissue in terms of lipid-water ratio and scattering during an intervention.

    摘要: The invention relates to optical probes for miniature applications, e.g. medical inspections and procedures or in industrial inspections, in particular a probe applying a confocal scanning-scanning endoscope. The probe comprises an optical guide (2), a first lens system mounted (4) on a distal end portion (2A) of the optical guide for focusing light from the optical guide, actuation means (6,7) for displacing the distal end portion and the first lens system to enable optical scanning, and a second lens system (9) fixed inside the probe to receive radiation from the first lens system. The second lens system is selected to enable a deflection of radiation from the first lens system in a direction corresponding to a direction of displacement of the first lens system by the actuation means. The second lens system can be a cheap negative lens, and the invention is thereby particularly useful for increasing the field of view (FOV) cheap, disposable optical probes.
