The simplification of calculations with assuring the sufficient accuracy in making tomography images of analyzed physical phenomenon should succeed in faster obtaining of results. This issue is important because the contemporary tomography is expected to bring real time, tomography images of dynamically changing environment. Taking into consideration growing ecology and safety demands, there is a...
The problem of the image reconstruction in Electrical Impedance Tomography (EIT) is a highly ill-posed inverse problem. The Chan-Vese method is an established model for numerical problems. In contrast to the traditional level set method, interfaces between the subdomains are represented as discontinuities in the level set function. Moreover, no more than one function is needed to represent any numbers...
Boundary Element Method for simulation of spatially homogeneous objects of electroencephalography and tomography is presented in this paper. The four layer spherical model (representing skin, skull, CSF layer and brain) of the real head approximated with isoparametric six nodes triangles was considered. For different kinds of boundary conditions formulation of the algebraic system of equations was...
