Grundriss der Allgemeinen ChirurgieThis chapter explains the magnetic resonance electrical impedance tomography (MREPT) technique used to image electrical properties at high frequencies. The chapter describes the MREPT data acquisition methods, current state-of-the-art image reconstruction algorithms, and experiments with phantoms, animals, and humans.

Modeling for Electromagnetic Characterization, Prediction, and Reconstruction, simplest form, modeling can be used to predict measurements of magnetic flux density (. in the case of MREIT or . fields in the case of EPT) based on realistic representations of the imaged object. Further, projected current density methods must refer to a uniform model of an imaged object in order

Magnetic Resonance Imaging Basics, a description of nuclear magnetic resonance (NMR) phenomenon and then gradually arrive at the mathematical expressions for MRI signal in spatial domain and k-space domain. Then we describe the image reconstruction methods typically used in MRI, the signal-to-noise ratio calculation methods in MRI,
