Skin lesion detection system based on propagation characteristics of multispectral light source in subcutaneous tissue

Abstract

The invention provides a skin lesion detection system based on propagation characteristics of a multispectral light source in subcutaneous tissue. The device is characterized by comprising a light control module (1), a broadband spectrum adjustable light source (2), a condensing lens (3), a first coupler (4), a transmission optical fiber (5), an optical path switcher (6), an irradiation path optical fiber (7), a measurement path optical fiber (8), a second coupler (9), an inclined angle light beam emergent optical fiber (10), a skin light spot acquisition fixing device (11), a light spot detection sensor (12), a photoelectric detector (13), a light power measurement module (14) and a data analysis module (15), and a display unit (16). The method can be used for multi-dimensional acquisition, analysis and modeling of propagation characteristic parameters of light beams with different wavelengths and intensities in subcutaneous tissue, can timely diagnose the early stage of skin lesion which does not present symptoms on the skin surface, and can be widely applied to the fields of skin tissue lesion diagnosis and the like.

Description

(1) Technical field [0001] The invention relates to a skin lesion detection system based on the propagation characteristics of a multispectral light source in subcutaneous tissue, which can be used for non-invasive diagnosis of early skin lesions in the epidermis and subcutaneous tissue, and belongs to the technical field of skin lesion diagnosis devices. (2) Background technology [0002] The advantage of non-invasive skin lesion detection is that it has no effect on the human body and is relatively safe. Skin lesions occur at three levels of skin epidermis, dermis and subcutaneous tissue. At present, the diagnosis of skin lesions is divided into two types. One is to take tissue biopsy from the lesion area or to observe by non-invasive and non-contact methods. In recent years, in order to alleviate the pain of patients, non-invasive detection methods have flourished. At present, common non-invasive skin lesions detection methods include dermoscopy, 5-helium ketovaleric aci...

Problems solved by technology

The method and structure can collect images about 300 μm below the surface of the tested sample, which cannot go deeper

It is impossible to judge the formation of diseased cell clusters such as early skin cancer

Yu Ye from Shanghai First People's Hospital and others used infrared temperature measurement to judge whether there are higher temperature cancer cells forming subcutaneously. , especially for basal cell carcinoma with insignificant early symptoms such as micronodular type, it is impossible to diagnose early lesion
