Abstract
Provided are a tomography apparatus and a method for reconstructing a tomography image. The method includes obtaining a plurality of raw data corresponding to a plurality of views by performing a tomography scan on an object and deblurring each of the plurality of raw data based on a point spread function (PSF) that varies according to locations in a field of view (FOV) in a gantry. The method also includes reconstructing a final tomography image in which a motion of the object is corrected from the plurality of deblurred raw data based on a motion vector indicating the motion of the object.
