Abstract
An electric properties tomography method for reconstructing a spatial distribution of electric conductivity (σ) from magnetic resonance image data representative of a magnetic resonance image of at least a portion of a subject of interest (), the spatial distribution covering at least a portion of the area of the magnetic resonance image, and the method comprising following steps:—segmenting the magnetic resonance image,—extrapolating acquired phase values, —replacing acquired phase values by the extrapolated phase values,—transforming into the frequency domain,—multiplying a frequency domain-transformed numerical second derivative by the acquired phase values and the frequency domain-transformed numerical second derivative by the extrapolated phase values, respectively, and—transforming the result of the multiplying into the spatial domain. Also covered are a corresponding MRI system and a software module.
