A Matlab Toolbox for Magnetic Resonance Electrical Impedance Tomography (MREIT): MREIT Toolbox

Magnetic Resonance Electrical Impedance Tomography (MREIT) is a relatively new imaging technique that allows tomographic imaging of electrical conductivity of biologically conductive objects. In this paper, we present software that has been implemented to accompany MREIT. The software offers various computational tools from preprocessing of MREIT data to reconstruction of cross- sectional conductivity and current density images of an object from MREIT data. The software named as MREIT Toolbox runs under the commercially available technical computation software called Matlab. The major routines in the toolbox include magnetic flux density computation, denoising of flux density maps, recovery of lost density signal, geometrical modeling tools, conductivity reconstruction, and current density reconstruction. The presented tools should be useful to researchers in the field of MREIT for studies of simulation, validation, and further technical development. The toolbox is available upon request made to the Impedance Imaging Research Center in Korea.
