Abstract: A radiography apparatus sequentially determines, on the basis of the positions of markers as time-sequential feature points (of a plurality of frames), positions at which the markers in the frames are displayed. This makes it possible to display a moving object while the position, direction and size thereof are properly set. Another advantage is that when a plurality of markers are extracted, information relating to the direction and size of the object is retained and the proximal and distal directions of the object and the length of a device (e.g., stent) can be intuitively determined from an image. Since positioning is performed using the plurality of positions of markers and the plurality of display positions, the position and direction of a corrected image to be finally displayed can also be set properly.

Abstract: An X-ray fluoroscopic imaging apparatus includes: an image generation element that generates the fluoroscopic images of the subject; an image processing element that executes an image processing to superimpose a plurality of fluoroscopic images that the image generation element continuously generates, and generates and displays the image denoting the movement locus of the marker that denotes the location of a stent introduced inside a body of the subject; and a region-of-interest setting element that set up the region-of-interest includes the movement locus relative to the superimposed image, in which the fluoroscopic images are superimposed one another.
