Problems solved by technology

In addition, this technology needs to be used in conjunction with an ordinary colposcope, and it cannot give a color image of a colposcope close to natural white light illumination.
Takes a long time (minimum 12 seconds) and low resolution (1 mm x 1 mm), higher resolution images take longer

Embodiment 1

[0067] Please also refer to figure 1 , Figure 4 with Figure 5 , an embodiment of a narrow-band multispectral fluorescent vaginal examination device of the present invention includes an image acquisition system 1, an image processing system 2, a light source system 3 and a cervical acetic acid coloring system;

[0068] The image acquisition system 1 is an area-array multi-channel narrow-band filter 14 that is closely attached to the imaging surface of a monochromatic image sensor 11, and the image acquisition system 1 includes an Highly integrated, area-array multi-channel narrow-band filters 14 arranged periodically with macro filter units as the period. This checkerboard-like multi-channel narrow-band filter is closely attached to or directly fabricated on the imaging surface of a sensitive monochrome image sensor 11 with low-light imaging capability in a microfabrication method (such as vacuum coating and microlithography technology, etc.) Above; the multi-channel narro...

Embodiment 2

[0079] Please also refer to figure 2 , Figure 4 with Figure 6 , an embodiment of a narrow-band multispectral fluorescent vaginal examination device of the present invention includes an image acquisition system 1, an image processing system 2, a light source system 3 and a cervical acetic acid coloring system;

[0080]The image acquisition system 1 includes a color image acquisition system 12 and a fluorescence image acquisition system 13, the fluorescence image acquisition system 13 includes an area array multi-channel narrow-band filter 14 and a monochromatic image sensor 11, the multi-channel narrow-band The optical filter 14 is closely attached to the imaging surface of the monochromatic image sensor 11; the present invention is in the image acquisition system 1 of the existing colposcope, when the optical signal from the vaginal opening and the cervix enters the color image sensor Add a semi-reflective half mirror on the light path. Specifically, a color image acquis...

Embodiment 3

[0099] Please also refer to image 3 , Figure 4 with Figure 7 , the embodiment of the narrow-band multispectral fluorescent vaginal examination device of the present invention includes an image acquisition system 1, an image processing system 2, a light source system 3 and a cervical acetic acid coloring system;

[0100] Described image acquisition system 1 is that an area-array multi-channel narrow-band filter 14 is close to the imaging surface of a color image sensor 11; there are inherent functional components (such as Figure four shown), the main difference is that a multi-channel narrow-band filter and the corresponding image processing system 2 are added adjacent to the color image sensor in the image acquisition system 1 of the existing digital colposcope or fluorescent colposcope.

[0101] The image processing system 2 is connected to the image acquisition system 1, and corrects, analyzes and processes the multi-channel narrowband images collected by the image acq...

Abstract

The invention discloses a narrow-band multispectral fluorescent vagina check device comprising an image acquisition system, an image processing system, a light source system and a cervix acetic acid coloring system; the image acquisition system is formed by clinging a planar array type multichannel narrow-band pass filter on an imaging surface of a monochrome image sensor; the image processing system is connected with the image acquisition system, is used for correcting, analyzing and processing a multichannel narrow-band image acquired by the image acquisition system, and is provided with a color image display for displaying a processing result; the light source system comprises a lighting source as a white cold light source and an excitation light source as a source with a peak value between ultraviolet light and blue light, the lighting source and the excitation light source are arranged tightly, and the light source system also comprises a light source switch for respectively controlling the lighting source and the excitation light source to switch on or off; and the cervix acetic acid coloring system is provided with an acetic acid atomization device for realizing uniform distribution of acetic acid on the surface of an observation part.

Description

technical field [0001] The invention relates to a narrow-band multi-spectral fluorescent vaginal examination device for screening, diagnosing, guiding laboratory tissue sampling and treatment of cervical cancer. Background technique [0002] Cervical cancer is the second most common malignant tumor in women, and there is a clear upward trend in China at present. International medical authorities have confirmed that cervical cancer is an infectious disease, a preventable disease, and the only cancer in the world that can be detected and cured early. Cervical cancer belongs to epithelial cancer, and the source of disease originates in the epithelium (mucosa). Cervical precancerous lesions, also known as cervical intraepithelial neoplasia, or CIN (cervical intraepithelial neoplasia), pathological examination of cervical tissue showed atypical hyperplasia. [0003] CIN can be divided into mild, moderate and severe. ① Mild dysplasia (anaplastic grade I): The arrangement of epi...
