【課題】 超音波造影剤注入に引き続き又は同時にＸ線造影剤を注入して超音波計測し、関心領域へ造影剤が流入したことを検知してから、Ｘ線による関心領域の血管像撮影を開始する血管撮影装置に関し、造影剤の関心領域への到達とＸ線ＣＴ撮影開始のタイミングを一致させ、精度のよい血管像を撮影することのできる血管撮影装置を提供する。 【解決手段】 予め関心領域に超音波を送受する貼着プローブを関心領域の表面に貼着しておく。超音波造影剤に引き続き又は同時にＸ線造影剤を前記被検体へ注入し、貼着プローブが受波した超音波に基づき超音波造影剤の関心領域への到達を検知する。到達が検知されると、関心領域の造影画像の撮影を開始するトリガ信号を出力する。 【選択図】 図１
