PROBLEM TO BE SOLVED: To provide an X-ray CT system obtaining determination information to avoid the generation of an overflow in a detection element, and also to provide a control program for the X-ray CT system.SOLUTION: The X-ray CT system includes: an imaging-condition setting part that sets CT-image imaging conditions, including an electric amount for driving and controlling an X-ray tube during CT imaging, based on a scanogram image that has been imaged by irradiating X-rays from the X-ray tube to a subject on a top board, that has been stopped at the first position or second position and a determining part that determines whether there are any detection elements that are expected to detect an X-ray dosage exceeding a predetermined value and outputs the determination result when a CT-image is imaged based on the set CT image imaging condition.COPYRIGHT: (C)2010,JPO&INPIT【課題】検出素子のオーバーフローの発生を回避するための判断情報を得ることが可能なX線CT装置及びX線CT装置の制御プログラムを提供する。【解決手段】天板上の被検体に対して第1位置又は第2位置に停止させたX線管からX線を照射することにより撮影されたスキャノ像を基に、CT像を撮影するときのX線管を駆動制御するための電気量を含むCT像撮影条件を定める撮影条件設定部と、定められたCT像撮影条件を基にCT像を撮影した場合、予め定められた値を超えるX線量を検出する検出素子の存在の有無を判定し、判定結果を出力する判定部と、を有する。【選択図】図1
