| Abstract | Radio Frequency-Localized Current Field (RF-LCF) technique of interstitial hyperthermia delivery is able to provide volumetric control of power deposition in tissue when segmented electrodes are used. However, in the present form this technique is not practical because it requires two separate implants for the same tumor: one for hyperthermia and the other for radiotherapy delivery (the lumen of RF electrodes if filled with wires necessary to control power to each segment and cannot be used for placement of radioactive sources). A hybrid implant for RF-LCF hyperthermia delivery for RF-LCF hyperthermia delivery was developed and studied theoretically and experimentally. In this implant, each segmented electrode is surrounded by four continuous electrodes that pass through vertices of 1.5/spl times/1.5 cm/sup 2/. These continuous electrodes can be used for placement of radioactive sources. The segmented electrodes pass through the center of each square and are used for volumetric control of power deposition. Thus, the proposed technique circumvents the major deficiency of the conventional volumetrically controlled RF-LCF hyperthermia. |

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.
