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.

Tomography apparatus and method of reconstructing tomography image

A tomography apparatus includes a data acquirer configured to obtain a first partial image and a second partial image of an object based on data that is obtained respectively at a first angular section corresponding to a first time and at a second angular section corresponding to a second time during a tomography scan of the object that is moving, a controller configured to determine first information indicating a motion amount of the object in a first area of an entire image based on the first partial image and the second partial image, and determine second information indicating a degree of blur of a point included in the object in the first area based on the first information, and an image processor configured to correct the first area based on the first information and the second information, and output a tomography image based on the corrected first area.
