Magnetic resonance electrical impedance tomography (MREIT) is a new medical
imaging modality visualizing static conductivity images of electrically conducting subjects. Recently, MREIT has rapidly progressed in its theory, algorithm, and experiment
technique and now reached to the stage of in vivo animal experiments. In this paper, we
present a software, named CoReHA 2.0 standing for the second version of conductivity
reconstructor using harmonic algorithms, to facilitate in vivo MREIT reconstruction of
conductivity image. This software offers various computational tools including preprocessing of MREIT data, identification of 2D geometry of the imaging domain and electrode
positions, and reconstruction of cross-sectional scaled conductivity images from MREIT
data. In particular, in the new version, we added several tools including ramp-preserving
denoising, harmonic inpainting, and local harmonic algorithm to deal with data from
in vivo experiments. The presented software will be useful to researchers in the field of
MREIT for simulation, validation, and further technical development.
