| Abstract | A knowledge-based data compression algorithm for dynamic positron emission tomography (PET) images has been developed previously (D. Feng et al., "An optimal image sampling schedule design for cerebral blood volume and partial volume correction in neurologic FDG-PET studies", The 29/sup th/ Annual Scientific Meeting of A & NZ Society of Nuclear Medicine, April 4-8, 1998, Melbourne, Australia, to appear in Australia and New Zealand Journal of Medicine), and it has been shown that this algorithm can greatly reduce image storage requirements in both spatial and temporal domains, while retaining medically relevant information. However, this algorithm has not yet been validated with real clinical dynamic image data. Here, the authors validated this algorithm in clinical dynamic brain PET studies using the [/sup 18/F] 2-fluoro-deoxy-glucose (FDG) tracer. Compression performance and image quality were evaluated. Results demonstrate that the storage requirements for dynamic PET image data can be reduced by more than 95%, without loss in diagnostic quality. Furthermore, use of this compression algorithm greatly reduces the computational complexity of further clinical image processing such as generation of functional images. It could benefit to the current expansion in medical imaging, and image data management. |

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.
