| Abstract | Cardiovascular disease (CVD) is one of the most prevalent cause of death in many countries. Computed Tomography Angiography (CTA) is a widely used imaging modality to diagnose and treat different types of CVD. Diagnosing stenosis in coronary artery using CTA data sets is a tedious and time consuming task. To overcome this difficulty we propose an automated segmentation system for stenosis detection on 2D projection images. The segmentation of coronary artery is achieved by techniques such as image smoothing, vessel enhancement, localized threshold and connected component labeling. Further, stenosis, if present, is identified by finding the discontinuities in the vessel by centerline extraction, calculating the thickness and the intensity of the vessel. The objective of the proposed system is to reduce the number of false negative responses by finding out all suspected parts of the coronary arteries for detailed and final investigations by medical experts. The performance of the proposed system has been evaluated by comparing the outcome with the ground truth given by the experts and this provides an average recall measure of 97%. |

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.
