PROBLEM TO BE SOLVED: To provide an X-ray imaging apparatus that can accurately reproduce a pixel value without complicated calculation for image connection even when dual energy subtraction photographing is performed using an X-ray focused in a slit shape.SOLUTION: An X-ray imaging apparatus for performing dual energy subtraction photographing includes: a lying table 13 for photographing a subject M in a laid state; an X-ray tube 31; a collimator 32 having a plurality of collimator leaves 33; an X-ray tube rocking part described later for rocking the X-ray tube 31 centering around a focus 39 in a body axis direction of the subject M; and a flat panel detector 11 for detecting X-ray passing through the subject M as an X-ray detector. |
