摘要： The present disclosure relates to an illumination system for endoscopic applications comprising at least one substantially monochromatic light source having a predefined central wavelength between 400 and 500 nm or between 500 and 550 nm, an optical transmission path adapted to guide light emanating from the light source to an endoscopic region of examination, and an optical band-rejection filter, wherein the illumination system is adapted to illuminate at least a part of the region of examination by generating autofluorescence in surrounding tissue, and the band-rejection filter is adapted to attenuate at least said light source wavelength to a viewer and wherein said light source is the single light source in the illumination system. A further embodiment relates to an endoscope for examining a body cavity comprising tissue, the endoscope comprising a source of light consisting of a substantially monochromatic light source having a predefined central wavelength between 400 and 550 nm, means for guiding light from the substantially monochromatic light source towards at least a part of the tissue, and at least one band-rejection filter adapted to attenuate at least said central wavelength, wherein the substantially monochromatic light source is configured to generate autofluorescence in the irradiated tissue such that the irradiated tissue is observable, and wherein the endoscope is configured to display at least a part of the irradiated tissue through said band-rejection filter. A system for photodynamic diagnosis and/or therapy of bladder cancer is further disclosed herein.
摘要翻译：本公开内容涉及一种用于内窥镜应用的照明系统，其包括至少一个基本单色光源，其具有在400和500nm之间或在500和550nm之间的预定中心波长，光传输路径适于将从光源发出的光引导到内窥镜检查区域和光学带阻滤波器，其中所述照明系统适于通过在周围组织中产生自发荧光来照射所述检查区域的至少一部分，并且所述带阻滤波器适于至少衰减所述光源波长到观察者，并且其中所述光源是照明系统中的单个光源。另一实施例涉及一种用于检查包括组织的体腔的内窥镜，所述内窥镜包括由具有400至550nm之间的预定中心波长的基本单色光源组成的光源，用于引导来自所述基本单色光源的光朝向所述组织的至少一部分，以及适于至少衰减所述中心波长的至少一个带阻滤波器，其中所述基本单色光源被配置为在所述被照射的组织中产生自发荧光，使得所述被照射的组织是可观察的，以及其中，所述内窥镜构造成通过所述带阻滤波器显示所述被照射组织的至少一部分。本文进一步公开了用于膀胱癌的光动力学诊断和/或治疗的系统。
