摘要： 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.

摘要： A tomography apparatus includes: an X-ray generator which emits X-rays; a controller which determines a first value based on a threshold dosage of the X-rays allowed for a subject and generates an absorbed-dose distribution diagram which indicates a location range of the subject in which, when the X-rays are irradiated to the subject based on an imaging condition, an absorbed dose of the X-ray has the first value; and an indicator showing the absorbed-dose distribution diagram.
