Abstract

A method for operating an X-ray computed tomography (CT) apparatus includes obtaining a first projection data set by scanning an area of interest with X-rays at a first time; obtaining a second projection data set by scanning the area of interest with X-rays at a second time; obtaining at least one item of difference data which includes a difference between a first item of projection data from among the first projection data set and a corresponding item of projection data from among the second projection data set; and determining a rescanning of the area of interest by using X-rays based on information relating to the difference data.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2012-0123097 filed with the Korean Intellectual Property Office on Nov. 1, 2012, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] One or more exemplary embodiments relate to a radiation imaging apparatus and a method for operating the radiation imaging apparatus. Background technique [0003] X-ray computed tomography (CT) apparatus is a device that can be used to scan an examination object (such as, for example, a body) by using a specific dose of X-rays, by measuring the X-rays passing through the examination object by using an X-ray detector, The X-ray absorptivity measured at each point of the inspection object is acquired, and thus an image is reconstructed using the acquired X-ray absorptivity. For this reason, the X-ray CT apparatus needs to perform X-ray photography for two-dimensional (2D) images to acquire images of one point of an insp...
