| Abstract | Most commercial ultrasound machines do not allow the researcher to acquire internal data, modify the signal processing algorithms or test a new clinical application. A software-based ultrasound machine could offer the needed flexibility to modify the ultrasound processing algorithms and evaluate new ultrasound applications for clinical efficacy. We have designed an ultrasound machine in which all of the back-end processing is performed in software rather than in hardware. This programmable machine supports all the conventional ultrasound modes (e.g., B mode, color flow, M mode and spectral Doppler) without any performance degradation. The frame rates and image quality of this programmable machine were evaluated and found to be comparable to commercial ultrasound machines. Due to its programmability, we were able to improve the accuracy of flow velocity estimation by integrating a new clutter rejection filtering method into the system. The machine also supports advanced features such as 3D volume rendering in software. Our results demonstrate that a software-based ultrasound machine can provide the same functionality for clinical use as conventional ultrasound systems while offering increased flexibility at low cost. |

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.
