This X-ray imaging apparatus is provided with an image controller for generating a composite image by superimposing a plurality of X-ray images. The image controller includes a detection processing unit configured to detect both a marker for indicating a position of a predetermined target object to be indwelled in a body of a subject and a device to be placed in the body of the subject separately from the predetermined target object, in the generated X-ray image. The image controller includes a composition processing unit configured to generate the composite image by superimposing the plurality of X-ray images based on the detected marker and the detected device.

X-ray imaging apparatus and x-ray image processing method

A radiation fluoroscopy apparatus detects a marker and includes a control element, an image generation elementthat generates an image including an embedded marker inside the body of the subject based on a transmitted X-ray. A device candidate detection elementdetects the candidate of the marker, the local structure detection elementdetects the local structure in the target region in a proximity of the candidate point of the marker, the device determination elementdetermines whether the local structure is the device such as the marker or not, the device location acquisition elementacquires the gravity center coordinate of the local structure, and the device tracking elementtracks the marker based on the location of the marker in each frame.
