| Abstract | Quantitative analysis of global and regional left ventricular function from short-axis multi-slice Cine MR imaging studies currently requires manual tracing of endo- and epicardial contours in many images. To circumvent the limitations which are associated with manual contour tracing procedures, a software package (MASS: MR Analytical Software System) has been developed with automated contour detection. The contour detection follows a model-based approach incorporating the assumption that contours and images exhibit a gradual change from phase to phase and from slice to slice. The user may interact with the automated contour detection to control the analysis procedure and to avoid the potential risk of error propagation. Compared to manually obtained results, the contour detection software accurately assessed endocardial volumes, epicardial volumes and ejection fraction (correlation coefficients: 0.90-0.97). Total average analysis time for a complete imaging study was 25 minutes.< |

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.
