| Description | The purpose of this paper is to describe a rule-based system named IBIS (Interpretation of Biomedical Images of the Slice type), which, starting from conventional image processing, can recognize slices and locate automatically their principal anatomical organs in nuclear magnetic resonance (NMR) images of the head. The main aspects of the system are: knowledge representation, with 3-D and 2-D aspects for anatomical description; error recovery and conflict resolution facilities at different backtracking levels; and a general system structure easy to extend to other application fields. Production rules are employed in order to define the criteria for deciding what action is to be performed on the basis of the current problem status. However, in order to obtain a more explicit and appropriate representation, anatomical knowledge has not been spread throughout the production rules, but it has been incorporated into an extended semantic network that well represents relational properties. The control structure consults production rules and, according to their content, activates the various processing procedures in order to attain the recognition goal. A strategy is applied that can be driven by data or models, depending on the processing phase and on progressive results. Applications of the system to different patients and slices are described and discussed. The importance of the paper lies basically in the methodological approach to image processing and interpretation, and in possible interesting applications to the medical field. |

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.
