| Abstract | To conduct experiments using HIFU, the position of the HIFU focus should be exactly defined. Due to variety of medium and inaccuracy of the focus, such operations are usually accompanied with ultrasound, MRI, or photo-acoustics to check the HIFU focus in real time. Commonly, the procedure is examining HIFU ultrasound in a water tank in advance, searching for the focus area formed in the water using diagnostic ultrasound. However, since the diagnostic ultrasound interferes with the ultrasound from HIFU, finding the exact focal point is extremely difficult. In this study, a new method for searching HIFU focus and calibrating the HIFU transducer is proposed, which employs a 6-DOF robot arm and a hydrophone. This new method for robotic calibration of HIFU transducer includes 3 steps as a whole: hardware calibration, ultrasonic signal processing, and searching for focused ultrasound signals. Compared with the position of the focal point using a simulated focus and found to evaluate the accuracy of the experiment. |

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.
