| Abstract | Shear wave elastography, often based on ultrasound imaging, has been used to provide mechanical information of the imaged biological tissue for assisting pathologic diagnosis. To improve the sensitivity and spatial resolution of shear wave imaging, several optical imaging modalities have been investigated and implemented. In this study, laser speckle contrast imaging (LSCI) is used for detecting shear wave propagation in a tissue-mimicking phantom. Shear wave is induced by acoustic radiation force generated using a single element focused ultrasound transducer, driven by an ultrasonic burst with 100 μs duration. This imaging technique has shown good accuracy in estimating the shear wave velocity, which is justified by a commercial ultrasound system, with the deviation found to be less than 6% for soft and hard phantoms. Furthermore, this imaging system has exhibit a good sensitivity for detecting small shear wave displacement (approximately tens of nanometer), as well as distinguish small variation in phantom stiffness. With improvement in imaging sensitivity and spatial resolution (315 μm achieved in this study), LSCI has potential for providing detailed elasticity distribution analysis. |

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.
