An X-ray fluoroscopic apparatus which extracts marker M portions from capturing image 80a~image 80n including the marker M to obtain template image 81a~ template image 81n is provided. When an examinee 57 starts to be treated, a fluoroscopy is made to a region including the marker M. Then, a template matching is made between a region 83 including the marker M of an image 82 captured every fixed time and a plurality of the template image 81a~ template image 81n. That is, a matching is made sequentially between the region 83 including the marker M of the image 82 captured every fixed time and all of the plurality of the template image 81a~ template image 81n.本發明提供一種X射線透視裝置,由拍攝包括標記M的圖像80a、80b、80c…80n,提取標記M部分而獲得模板圖像81a、81b、81c…81n。於開始對受檢者57治療時,對於包括標記M的區域進行透視。繼而,對於每隔固定時間拍攝的圖像82中的包括標記M的區域83,利用多個模板圖像81a、81b、81c…81n進行模板比對。即,對於每隔固定時間拍攝的圖像82中的包括標記M的區域83,使多個模板圖像81a、81b、81c…81n全部依序比對。80a~80n、82‧‧‧圖像81a~81n‧‧‧模板圖像83‧‧‧區域M‧‧‧標記
