Abstract
The invention discloses a sub-diffuse tissue domain spatial resolution optical detection system for rapid diagnosis of the cervical cancer. The sub-diffuse tissue domain spatial resolution optical detection system comprises a light source system, a signal acquisition system and an optical fiber probe, wherein the light source system is used for generating incident light with multiple wavelengths;the optical fiber probe is used for conducting the incident light generated by the light source system to irradiate cervical tissues and receiving reflected light of the cervical tissues; the signal acquisition system is used for receiving the reflected light from the optical fiber probe and converting the reflected light into an electric signal; the optical fiber probe comprises an incident optical fiber and a plurality of receiving optical fibers with different source detection distances; the signal acquisition system comprises a light receiving and processing module and a signal acquisitionmodule; the light receiving and processing module comprises a photoelectric sensor module and an amplifying and filtering circuit module; the amplifying and filtering circuit module amplifies and filters each path of input electric signal and then outputs the electric signal to the signal acquisition module; and the signal acquisition module converts an input analog quantity signal into a digitalsignal and then outputs the digital signal. According to the sub-diffuse tissue domain spatial resolution optical detection system, noninvasive, real-time and efficient mucosal tissue lesion early detection is realized.
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...
