Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 一つの診断用光源だけを使用して、癌病巣部 の蛍光像と診断部位の全体像を別々に、または時分割し て同一画面上に表示し観察できる小型で取扱い易く安価 な癌病巣診断装置を提供する。 【構成】 水銀灯1と、この水銀灯1から発する光のう ち光感受性物質特有の蛍光を効率よく励起することがで きる波長付近の光だけを透過する光フィルター2と、水 銀灯1から発する光を光フィルター2を透過したり素通 ししたりして、診断部位20に照射する光の波長分布を 変える波長切替え手段4と、照射する光を病巣部Aに導 く光伝送路5と、病巣部Aを観察するための画像伝送路 6と、この画像を表示する画像表示手段8とを備えるこ とにより、一つの光源1で癌病巣部Aの蛍光像と周辺部 Bを含めた診断部位20の全体像を別々に、または時分 割して得ることができる。 (57) [Summary] [Purpose] A compact size that allows the fluorescent image of the cancerous lesion and the entire image of the diagnostic site to be displayed separately or in time division on the same screen using only one diagnostic light source. A cancer lesion diagnostic apparatus that is easy to handle and inexpensive. [Structure] A mercury lamp 1, an optical filter 2 for transmitting only light in the vicinity of a wavelength that can efficiently excite fluorescence peculiar to a photosensitizer among lights emitted from the mercury lamp 1, and an optical filter for light emitted from the mercury lamp 1. The wavelength switching means 4 for changing the wavelength distribution of the light radiated to the diagnostic site 20 by passing through or passing through the diagnostic region 20, the optical transmission path 5 for guiding the radiated light to the lesion A, and the lesion A are observed. By providing the image transmission line 6 for this purpose and the image display means 8 for displaying this image, the fluorescence image of the cancer lesion A and the whole image of the diagnostic region 20 including the peripheral portion B are separated by one light source 1. , Or in a time-sharing manner.
