摘要： A optical Biopsy method and an apparatus are used in the diagnosis of precancerous lesion for locating the place and determining the level of malignant tumor. The apparatus comprises light source (1, 10) a light channel system, an endoscope (21) and a circuit system. The light sources include an excited light (1) and a cold light source (10). The cold light source and the excited light in the light channel system go through the end of the light guide of the endoscope via optical fiber bundle and irradiate the tested living tissue (22). The white light image signal and the intrinsic fluorescence image signal reflected from the tested living tissue (22) are received by a weak fluorescence CCD (6) that tightly connects to the end of the endoscope (21) and then transmit to the circuit system via a signal wire (9) to produce the image in the display (17). The weak fluorescence signal reflected from the tested living tissue (22) is transmitted to the circuit system via the weak fluorescence fiber bundle (4) protruding from the forceps hole of the endoscope to produce the spectrum image (16).

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.
