EPTlib – A library for electric properties tomography

EPTlib is an ongoing project for an open-source extensible C++ library collecting implementations of magnetic resonance-based electric properties tomography (EPT) methods. It is freely distributed and includes a terminal application for a simple ready-to-use adoption of the implemented methods.

EPT is a magnetic resonance-based quantitative imaging technique that estimates non-invasively the distribution of the electric properties, conductivity and permittivity, in the human body at the Larmor frequency of the used magnetic resonance imaging scanner. In the literature, a plethora of different methods has been proposed implementing EPT. Most of them are based on the elaboration of the scanner transmit sensitivity, acquired with a B1-mapping technique, and transceive phase, acquired as the phase of complex images obtained with common MRI sequences.

Currently, EPTlib implements three stable methods:

• Helmholtz-EPT,
• convection-reaction-EPT
• gradient-EPT.
