PROBLEM TO BE SOLVED: To easily provide focused images with less blur at least even when a dental arch is off a reference object plane.SOLUTION: A dental X-ray imaging equipment includes: an X-ray irradiation part 110 for irradiating a subject O with X-rays; an X-ray detection part 120 for outputting electric signals of a digital amount according to incident X-rays at a fixed frame rate; a turning arm 3 for moving the pair of the X-ray irradiation part 110 and the X-ray detection part 120 around the subject while the X-ray irradiation part 110 and the X-ray detection part 120 are opposite to each other with the subject O interposed between them ; a storage means 22 for successively storing, as frame data, photographic image signals for tomosynthesis output by the detection part 120 as the turning arm 3 moves the X-ray irradiation part 110 and the X-ray detection part 120 around the subject O; and an image processing means 20 for performing image reconstruction arithmetic operation based on the frame data stored in the storage means 22 and obtaining panoramic images. |
