| Abstract | Chirp pulse microwave computed tomography (CP-MCT) is a modality for microwave imaging of biological objects. By using the high-resolution model, which uses the chirp pulse signal from 2 GHz to 3 GHz, diagnosis of an early stage breast tumor has been attempted mainly by numerical simulation. However, the FDTD-based numerical simulation showed that only diagnostic information provided by the tomographic images was not sufficient for localizing the tumor in the breast fat tissues. This is mainly due to the strong scattering at the surface of the breast and the boundary between the tumor and surrounding fat tissues because of the big difference in those permittivity values. To gain the compensative information, we have investigated feasibility of the breast radar, which provides the dosimetric image according to the same measurement principle as CP-MCT. The chirp pulse microwave breast radar (CP-MBR) can provide tumor information projected onto the imaging plane of CP-MCT. The numerical simulation of the breast radar shows that the integrated use of those microwave imaging systems is useful for localizing the early stage tumors in the breast. |

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.
