| Abstract | In this paper, we propose a new shock filter algorithm for the thinning of hyperechoic structures observed on ultrasound (US) images of the equine superficial digital flexor tendon (SDFT). Implementation of the new algorithm is presented and applied on in vivo US data sets of a healthy and of an injured SDFT scanned with 7.5 MHz linear array transducer (SSD-2000-7.5, Aloka). Quantitative and qualitative results on the enhanced images show a coherent distribution of SDFT fiber bundles. In the case of normal SDFTs, the calculated number and area were respectively 48plusmn13 and 1.39plusmn0.48 mm . In the case of injured SDFTs, the calculated number and area were respectively 40plusmn9 and 1.80plusmn0.68 $mm^{2}.$ The 3D reconstruction of the SDFT allowed a better assessment of the fiber bundles alignment along the SDFT loading axis, as well as the injured areas. In conclusion, segmentation results demonstrated the potential of the new thinning algorithm on the SDFT structure characterization. |

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.
