| Abstract | Placement of N bars around the head of subject during an MR or a CT imaging session provides physicians and neurosurgeons with an analytical ability for preoperational target position determination in surgical planning. Since axial slices yielded by the system mentioned above has 9 N bar spots, where the actual length between them is known, determination of the position of a point can be calculated by N bar points with respect to any pre-selected origin. Even though, X-Ray CT and MRI are both complex, developed imaging modalities, neither of them can be defined as perfect because of their limitations. Namely, MR imaging is fine for soft-tissue filming, which makes it a strong candidate for neurosurgeries, where detailed imaging is important. Here, CT is not as good as MRI. On the other hand, MRI is limited due to, mostly, chemical shift, field non-uniformity, for preoperational target determination, hence CT imaging becomes more appropriate for such a purpose. Our goal is to integrate brain atlases and CT images to overcome the drawbacks mentioned above by developing a tool providing the neurosurgeon with a preoperational, target determination method by the atlas and CT image registration capability of the tool. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
