Our company's "SPICM-DNA Automatic Cell Tumor Screening and Analysis System" is an internationally advanced early detection system for cervical cancer. This product was introduced by Dr. Liu from the United States into the world advanced technology of American depth spectroscopy and imaging analysis. After five years' research, we have developed a new generation of products with independent intellectual property rights in combination with Wuhan University Scientific Instrument Engineering Technology Center, Hubei Spectrum and Imaging Technology Research Center, tongji hospital and Shandong Family Planning Commission. At the same time, the system embodies the valuable experience of more than 0/00 authoritative experts in gynecology and pathology in China. 200 1 this technology has been funded by the tenth five-year major scientific and technological research project, and the state supports 4 million yuan as research and development funds. At the end of 2003, it was successfully developed and accepted by experts organized by the Ministry of Science and Technology, and was awarded the invention patent certificate issued by China National Intellectual Property Administration (ZL2003101665438). In 2004, the clinical application in tongji hospital was 13 1 case, and the coincidence rate with manual examination reached 100%.
