Abstract
Magnetic resonance-based electrical properties tomography (MREPT), uses information of the \( B_{1}^{ + } \) field distribution in MRI, and computes electrical properties relative permittivity and electrical conductivity via the Helmholtz equation. The method can be done using standard MRI sequences, boosting the method into a more realistic clinical environment. MRI images need to undergo certain image pre-processing to correct ailments like noise and phase shifting. Recent publications on the topic report encouraging results and give a detailed explanation on the theory in which the process is based. However, little or none explanation is given to the processing to which the standard MRI images need to undergo in order for the method to be correctly implemented. Emphasis will be put on processing and corrections that needed to be applied to the retrieved MRI images to arrive to the results that are here reported.
