PROBLEM TO BE SOLVED: To provide an X-ray device that contributes to reduction of the burden on patients in X-ray imaging.SOLUTION: The X-ray device includes an X-ray source 40 that generates X-rays, a storage part 13 for storing an X-ray detector 4 that detects X-rays, and a heating element that produces heat when receiving power supply, e.g. a power supply device 15. During warm-up operation, the heat generated from the power supply device 15 increases the temperature of the X-ray detector 4 stored in the storage part 13.COPYRIGHT: (C)2014,JPO&INPIT【課題】X線撮影時における患者負担の軽減に寄与するX線装置を提供する。【解決手段】X線を発生させるX線源40と、X線を検出するX線検出器4を収納するための収納部13と、電源が投入されると発熱する発熱体、例えば電源装置15と、を含む。そして、暖気運転中に、電源装置15から生じる熱により収納部13に収納されたX線検出器4の温度を上昇させる。【選択図】図1
