    Abstract: The present disclosure provides an X-ray imaging apparatus and control method thereof, for guiding the user to intuitively recognize an actual dose of X-rays and select a proper dose, ultimately a condition for low dose of X-ray irradiation by providing the user with information about an actual X-ray dose to which an X-ray filter effect is reflected. In accordance with an aspect of the disclosure, an X-ray imaging apparatus includes: an X-ray source configured to generate and irradiate X-rays according to an X-ray irradiation condition including at least one of a tube voltage, a tube current, or a filter; a display configured to provide a graphic user interface to receive a choice about the X-ray irradiation condition; and a controller configured to obtain a parameter that represents a dose of radiation, to which an influence of the filter is reflected, based on the selected X-ray irradiation condition and control the display to display the parameter.
