A theoretical study on the 1-D reconstruction algorithm of inductive magnetic resonance electrical impedance tomography(MREIT) is given by this article. The computing method of the forward problem and the reconstruction equations of the inverse problem are proposed by using the concentrical disk model. Numerical simulations are performed to test the algorithm for both noise-free and noisy cases. It can be seen as the theoretical basic for the future study on inductive MREIT.
