Abstract
An apparatus, a method, and a recorded medium for conductivity and susceptibility reconstruction are disclosed. The apparatus for conductivity and susceptibility reconstruction includes: a susceptibility reconstruction part configured to reconstruct a susceptibility from a change in phase according to an increase in time of a multi-echo gradient echo image; a zero echo phase estimation part configured to estimate a phase at zero echo time based on a linearity of the phase change; and a conductivity reconstruction part configured to reconstruct a conductivity from the estimated zero echo phase. According to an embodiment of the invention, a multi-echo gradient echo sequence is used to not only obtain in vivo susceptibility but also obtain conductivity simultaneously. Also, an embodiment of the invention can improve the accuracy of the susceptibility measurements.
