<p>Magnetic resonance-based electric properties tomography</p>
<p>The example shows the uncertainty evaluation, under repeatability conditions, of a technique for Electric Properties Tomography (EPT), a quantitative imaging method based on Magnetic Resonance Imaging (MRI). Repeated acquisitions of MRI scans of a homogeneous cylindrical phantom are analysed with appropriate statistical techniques to evaluate the variance-covariance matrix of the EPT input. The latter is then propagated through the EPT technique according to the law of propagation of the uncertainty as described in the GUM [Activity A2.3.2].</p>

The example relies on the implementation of phase-based Helmholtz EPT collected in the open-source C++ library EPTlib 0.1.1 (https://eptlib.github.io/), developed in the framework of the EMPIR Project 18HLT05 QUIERO (https://quiero-project.eu/).
