PROBLEM TO BE SOLVED: To improve operability relating to mutual switching between complete imaging and partial imaging.SOLUTION: The X-ray imaging device includes: an X-ray source 1 an X-ray detector 5 an X-ray diaphragm 3 with a variable aperture for limiting an irradiation field of X-ray applied to a subject from the X-ray source an imaging control unit 9 controlling the X-ray irradiation from the X-ray source and the X-ray diaphragm so as to be in a first condition where the X-ray is applied to the subject in the first irradiation field, controlling movement of the X-ray diaphragm so as to be in a second condition where the X-ray is applied to the subject in a second irradiation field which is an irradiation field narrower than the first irradiation field and also controlling the X-ray irradiation from the X-ray source and a switch unit 20 capable of selecting the first condition or the second condition.COPYRIGHT: (C)2015,JPO&INPIT【課題】全面撮像と部分撮像との相互の切替に関する操作性を向上すること。【解決手段】本実施形態に係るX線撮像装置は、X線源1と、X線検出器5と、X線源から被検体へ照射するX線の照射野を限定するために開口可変のX線絞り3と、X線を第1の照射野で被検体に照射する第1の状態となるようにX線源からのX線照射とX線絞りとを制御し、X線を第1の照射野より狭い照射野である第2の照射野で被検体に照射する第2の状態となるようにX線絞りを移動制御するとともにX線源からのX線照射を制御する撮像制御部9と、第1の状態、第2の状態を選択操作可能なスイッチ部20とを具備する。【選択図】 図1
