| Abstract | This paper is deals with the implementation of autofluorescent excitation-emission matrices for the differentiation of cervical tissue. Autofluorescence diagnosis is characterized by the stimulation of endogenous fluorophores, such as, collage, NADH, and FAD in normal and abnormal tissue. !t has minimum invasion and it is in real time. In this research, we developed a small autofluorescence spectra measurement system. It consists of a sensitive PMT with a double gratings spectrometer, a Y type fiber including 18-excitation to 19-emission fibers, and xenon lamp with monochromate as multi-wavelength light source. We utilized this autofluorescence spectra and excitation-emission matrices (EEM) in cervical cancer study and measured normal and abnormal tissues (cervical intraepithelial neoplasia, CIN squamous cell carcinoma: SCC). EEM represented multi-excited wavelengths induced by different range wavelength of the emission. It allows us to get more information about tissues' characteristic. We used partial least squares (PLS) to analyze these data of the spectra and EEM. The result shows that the diagnostic ability by autofluorescence technology can be applied to ClN and using PLS analyzed pathological changes of the cervical tissue has a discriminative property. We also got high sensitivity and specificity to distinguish between normal endo and exo cervix by combining EEM and PLS . In the future, we will build autofluorescence EEM database for clinic diagnosis information. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
