Abstract

This work provides an improved image reconstruction technique, oblique slice magnetic resonance electrical impedance tomography (OS-MREIT), which can provide any cross-sectional conductivity distribution images with any type of MRI scanner. The OS-MREIT method can obtain conductivity distribution images using one component of magnetic field induced by injected currents with rotating subject once, and in the two-dimensional case, the conductivity distribution image can be reconstructed without rotating subject. The results of OS-MREIT studies performed with homemade C-shaped open permanent magnet MRI scanner are also presented in this work.
