| Zusammenfassung: | PROBLEM TO BE SOLVED: To reduce unnecessary exposure of a subject in an X-ray photography system.SOLUTION: An X-ray photography system comprises: an X-ray tube for applying X-rays; an X-ray detector for detecting the X-rays; an optical photography unit for performing optical photography of a subject, and collecting distance image information of the subject; a photography region setting unit for setting a photography region included in the subject; and a photography condition setting unit for calculating a body thickness of the photography region on the basis of the distance image information, and setting a photography condition depending on the body thickness.SELECTED DRAWING: Figure 2
【課題】Ｘ線撮影システムにおいて、被検体に対する不要被曝を低減すること。【解決手段】Ｘ線撮影システムは、Ｘ線を照射するＸ線管と、Ｘ線を検出するＸ線検出器と、被検体の光学撮影を行なって被検体の距離画像情報を収集する光学撮影部と、被検体に含まれる撮影部位を設定する撮影部位設定部と、距離画像情報に基づいて撮影部位の体厚を算出し、体厚に対応する撮影条件を設定する撮影条件設定部と、を有する。【選択図】 図２ |
