| Abstract | The magnetoacoustic tomography with magnetic induction (MAT-MI) is a hybrid imaging modality proposed to reconstruct the electrical impedance property in biological tissue by integrating magnetic induction and ultrasound measurements with high resolution. One of the major problems of MAT-MI is the singularity problem and its numerical errors caused by singular MAT-MI acoustic sources at conductivity boundaries and interfaces. In order to achieve more computational accuracy, especially on the conductivity boundaries and interfaces of inclusions, we have developed a forward solver in MAT-MI to compute the forward problem with generalized finite-element method (GFEM) in this paper. The novelty of this paper relies on the first adaption of GFEM in MAT-MI computation. Using the solver, the distribution of the eddy current and the distribution of the acoustic source are accurately computed in the object with computer simulation. The results demonstrate the feasibility of the forward solver in MAT-MI. In the forward solution, it is capable of achieving good accuracy and stability using our computation model with GFEM. |

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.
