1. Technical Field
Apparatuses and methods consistent with exemplary embodiments relate to an X-ray imaging apparatus and a method of controlling the same, and more specifically, to an X-ray imaging apparatus that reconstructs a current frame using previous frame information and a method of controlling the same.
2. Description of the Related Art
An X-ray imaging apparatus is an apparatus capable of obtaining an internal image of an object by radiating X-rays onto the object and collecting the X-rays transmitted through the object. Because the permeability of objects, materials, and/or elements within the object differ with regards to allowing X-rays to pass through depending on properties of substances composing the object, it is possible to image an internal structure of the object by detecting an intensity or a strength of X-rays transmitted through the object.
In order to provide a level of safety from the X-ray imaging apparatus, reducing a dose of X-rays incident on the object is recognized as an important issue and thus a great deal of research and development for reducing an X-ray dose is underway. One technological implementation for reducing an X-ray dose includes a method of radiating X-rays onto only a region of interest which has been generally adopted.
