The invention discloses a sub-diffusion tissue domain spatial resolution optical detection system for rapid diagnosis of cervical cancer, comprising a light source system, a signal acquisition system and an optical fiber probe; the light source system is used to generate incident light of various wavelengths; the optical fiber probe is used to conduct a light source system The generated incident light is used to irradiate the cervical tissue and receive the reflected light of the cervical tissue; the signal acquisition system is used to receive the reflected light from the fiber optic probe and convert the reflected light into an electrical signal; Receiving optical fiber; the signal acquisition system includes a light receiving and processing module and a signal acquisition module; the light receiving and processing module includes a photoelectric sensor module and an amplification and filtering circuit module; the amplification and filtering circuit module amplifies and filters each input electrical signal and outputs it to Signal acquisition module; the signal acquisition module converts the input analog signal into a digital signal and outputs it. The invention realizes non-invasive, real-time and high-efficiency early detection of mucosal tissue lesions.
Description
technical field [0001] The invention relates to the field of photoelectric detection technology in the technical field of biomedical engineering, in particular to a subdiffusion tissue domain space resolution optical measurement system for rapid diagnosis of cervical cancer. Background technique [0002] At present, cervical cancer is the second most common female cancer in the world. There are about 530,000 new cases of cervical cancer in the world every year. Due to factors such as economic conditions, race and geography, the incidence of cervical cancer in developing countries is lower than that in developed countries. 6 times, with 50% of cases occurring in China and India. Studies in recent years have shown that the incidence of cervical cancer is on the rise, and the age of onset is also tending to be younger. It takes about ten years for HPV infection to develop into invasive cancer. Therefore, regular prevention and screening and timely treatment can effectively pre...
