ABSTRACT:
An object of the invention is to provide a dual-purpose X-ray imaging apparatus capable of partial CT imaging in addition to panoramic tomographic imaging. Another object of the invention is to provide a dedicated partial X-ray CT imaging apparatus. An X-ray imaging apparatus comprises an X-ray source 28 which irradiates an object with X-rays; an image sensor 38 which detects X-rays having passed through the object; a support arm 24 which supports the X-ray source 28 and the image sensor 38; and a plurality of motors for moving the support arm 24. These motors move the X-ray source 28 and image sensor 38 along a CT image formation locus in the CT mode, and the X-ray source 28 and the image sensor 38 along a panoramic image formation locus in the case of the panorama mode.
