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.

Abstract: Provided are a computed tomography device and a computed tomography method. The computed tomography device includes a gantry and an image processing processor. The gantry includes a light source for irradiating light, a detector disposed facing the light source and for receiving the light, and an arm for supporting the light source and the detector. The image processing processor receives a two-dimensional detection image for a subject from the detector. The image processing processor converts the received two-dimensional detection image to two-dimensional detection image data. The image processing processor generates three-dimensional reconstruction image data from the two-dimensional detection image data. A computed tomography device and a computed tomography method according to the inventive concept correct an error of a gantry movement path to provide a stable three-dimensional reconstruction image.
