| Abstract | Recently, there has been increasing concern regarding the safety of exposure to RF electromagnetic fields in pregnant females and their fetuses. Therefore, we acquired fetal MRI images from pregnant women during the second and third trimesters of pregnancy and newly developed six fetal computational models at 20, 23, 26, 29, 32 and 33 weeks of pregnancy on the basis of the acquired images. The fetal models consist of about 20 different tissue types. These tissues were segmented by medical staffs using both manual and semiautomatic segmentation techniques from fine-resolution images acquired by 3D-ture FISP (Fast Imaging with State Precession) sequence. The works were performed under the supervision of a pediatric radiologist. The number of tissues and the spatial resolutions of the fetal models are better than those of models previously developed. This paper outlines the high-fidelity computational models of human fetuses during the second and third trimesters of pregnancy. |

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.
