Abstract
A radiography apparatus is constituted by an image pickup unit including an X-ray source for irradiating cone shaped X-ray beams to a patient under examination and an image receptor disposed opposite the x-ray source for receiving x-ray image data of the patient by the irradiated cone shaped x-ray beam; a cylindrical ring which carries the image pickup unit, defines a sufficient space to receive the patient therein so as to permit relative positional change of the patient with respect to the image pickup unit and is supported so as to permit rotation around its center axis; a second arm, an image pickup unit; a first video image processing unit; a second video image processing unit; and a change-over device which changes-over the x-ray image data obtained from the image pickup unit either to the first video image processing unit or to the second video image processing unit, whereby a three-dimensional x-ray image of the patient is obtained depending on necessity during an IVR while temporarily resting or interrupting the IVR.
