    摘要： This invention relates to a diagnostic apparatus and particularly to an apparatus for the diagnosis of malignant tumor and the method of using the apparatus for diagnosis. The apparatus employs an ultraviolet light source with an emitting waveband of 3000A-4000A. Light from the light source is transmitted through a bundle of quartz optic fibers to the surface of the tumor, whether benign or malignant, to stimulate it, which then generates a specific intrinsic fluorescence spectrum. The intrinsic fluorescence spectrum reflected from the surface of the tumor is transmitted by a second bundles of glass fibers placed near it to a color resolution means, then processed by a scanning means and a circuit means, and displayed recorded by a display recording means. The display may be a graphic presentation of the intrinsic fluorescence spectrum of the tumor that is tested. If the graphic presentation displayed includes a single peak within the range of the blue color band, it indicates that the tumor being tested is benign. If however, a second peak appears within the range of the red color band of the graphic presentation it is a characteristic peak of malignancy, indicating the existence of a malignant tumor. The presence of the red color can be established by eye rather than a complex color resolution system.
