This X-ray imaging device sequentially determines that m- continuous structure refers to (multiple frames) at that time based on the position of label, when being shown in the position of the label in frame. This makes to show a mobiles, while position, direction and its size are suitably set. Another advantage is when multiple labels are extracted, and the information in the direction and size that are related to object is retained, and the proximal end of object and the length of distal direction and an equipment (for example, stent) can intuitively be determined according to an image. Due to using multiple positions of label and multiple display positions to execute positioning, the corrected position of an image being finally demonstrated also can suitably be set with direction.
