| Abstract | At present, the diagnosis of brain oedema and brain hemorrhage is usually given according to the examination by CT or MRI. Although these methods can reflect the conditions of patient accurately, they are not proper for warding due to their inconvenience and high cost. Study shows there is interdependence between brain impedance and Brain hemorrhage, so that the brain impedance can be a sensitive indicator for brain hemorrhage. In this paper, the electromagnetic characteristic of brain impedance under low frequency current source and the electrical conductivity property of skull are presented. A new method of examining brain edema through brain electrical impedance topographic mapping (BEITM) is presented in this article, and BEITM is used to display brain electrical impedance with picture mode. Network topology structures used in BEITM are also reviewed. According to topology, we discuss the drawing algorithm based on a single triangle unit. Some patients have been examined and a lot of clinical data have been got, according to which Brain electrical impedance topographic was constructed by computer at last, functional imaging has been implemented. Clinical case analysis compared with CT photograph and repeatability of steady patient has proved the method is feasible. |

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.
