PHOTODYNAMIC DIAGNOSIS APPARATUS PROVIDED WITH COLLIMATOR |
摘要 |
An object of the present invention is to provide a PDD diagnosis apparatus that even if there is a distance from an irradiation portion of an optical fiber to a diseased tissue, enables provision of a fluorescence detection sensitivity equivalent to that in a case where irradiation is provided in such a manner that the irradiation portion of the optical fiber is brought close to the diseased tissue. A diagnosis apparatus including: a light source unit that emits excitation light to a photosensitizing substance accumulated in a diseased tissue; a detection unit that detects fluorescence produced from the photosensitizing substance; and an excitation light irradiation/fluorescence detection optical fiber including an output/input end with a collimator connected thereto, in which the excitation light emitted from the light source unit is guided to the excitation light irradiation/fluorescence detection optical fiber, and the excitation light output from the output/input end is provided in such a manner that the excitation light is collimated by the collimator and excites the photosensitizing substance accumulated in the diseased tissue; and the fluorescence produced by the photosensitizing substance excited by the excitation light is input from the output/input end via the collimator, and the input fluorescence is guided to the excitation light irradiation/fluorescence detection optical fiber and the fluorescence produced from the photosensitizing substance is detected in the detection unit is used. |
