Abstract: Provided are an image system and an image reconstruction method using the same. The image system includes an image scan device, a spectrum signal generation device, and an image recovery device. The image scan device generates a magnetic particle detection signal on the basis of an induced magnetic field induced from a magnetic particle. The spectrum signal generation device transforms the magnetic particle detection signal to a detection spectrum signal on the basis of a two-dimensional Fourier transform kernel. The image recovery device generates an image signal on the basis of the detection spectrum signal and a system matrix. According to the inventive concept, a data amount for image reconstruction may be ensured.
