| Abstract | Ultrasound (US) guided biopsy is a medical procedure routinely performed in clinical practice. This task could be performed by robotic systems to improve the precision in the execution and then the safety for the patient. Both robotic and human procedures could greatly benefit from real-time localization of the needle in US images. This information could guide the robot or the specialists to the correct target point avoiding critical structures. Unfortunately US data provide very low quality images of the needle making this task quite complex, even more if you want to perform the localization on-line during the image acquisition. In this work we present a needle localization method able to extract the needle orientation and the tip position in real time from B-mode US images. To evaluate the performance of the algorithm in a precise way we use an optical tracking system to measure the position and the orientation of the needle and the US probe. In such a way the comparison is not human dependent (i.e. there are no radiologists manually selecting the needle tip) and fully repeatable. The results show an improvement in term of localization accuracy compared to previous works in literature. |

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.
