X-ray image apparatus and device for and method of calibrating an X-ray image apparatus

摘要

A calibration device (140) for calibrating an X-ray image apparatus includes a receiving unit (200) for receiving an image captured by a detection unit (108) of the X-ray image apparatus (100) under reference conditions, an analyzing unit (201) for analyzing the captured image to derive gain correction information, and a calibration unit (202) for providing calibrating information for calibrating the X-ray image apparatus (100) based on the derived gain correction information disregarding gain correction of a heel effect.
