Abstract
The present invention relates to a device and method for reconstructing low-frequency conductivity images using MRI without current injection. In the device according to the present invention, low-frequency conductivity is deduced using high-frequency conductivity obtained using MR-EPT, the calculated directional tensor of ions from the water diffusion tensor in a subject, and the volume fractions and diffusion coefficients of the intracellular/extracellular spaces, and low-frequency conductivity images are reconstructed based on the deduced low-frequency conductivity. According to the present invention, low-frequency conductivity images in a subject to be measured such as the human body and an object may be reconstructed using an MRI device without applying current to the subject.
