摘要： An X-ray tube and a flat panel X-ray detector (FPD) are constructed movable parallel to each other in the same direction along a body axis which is a longitudinal direction of a patient. The X-ray tube intermittently emits radiation and the FPD detects radiation transmitted through the patient irradiated intermittently whenever the X-ray tube and FPD move every pitch. X-ray images O1, O2, . . . , OI, . . . , and OM are decomposed for every pitch noted above. The decomposed images are composed for each projection angle to obtain projection images P1, P2 and so on. Therefore, a sectional image with a long field of view in the longitudinal direction can be obtained by carrying out a reconstruction process based on the composed projection images.

摘要： Provided is a method of removing a moiré in a fluoroscopic X-ray image that preliminarily complements a defective pixel with no disturbance in regularity of a moiré pattern to ensure that no trace of the defective pixel and no ghost thereof create even when the fluoroscopic X-ray image contains the defective pixel. The method of removing the moiré in the fluoroscopic X-ray image according to this invention includes a moiré frequency derivation section that determines frequency of the moiré that appears in the fluoroscopic X-ray image, a defective pixel preliminary complement section that forms a preliminary complement image, a moiré removal section that conducts frequency analysis of the preliminary complement image to form a moiré removed image, an image smoothing section that that performs an image smoothing process to the preliminary complement image to form a smoothed image suitable for complement of the defective pixel, and a first defective pixel recomplement section that recomplements the defective pixel by superimposing the moiré removed image on the smoothed image.
