An x-ray apparatus uses an x-ray tube which is pivoted about a pivot axis to provide scanning of an x-ray beam. The pivot axis passes essentially through the center of the focal spot on the target surface of the anode of the tube, is essentially perpendicular to the anode-cathode axis, and is essentially parallel to a film plane defined by the x-ray film. The scanning of the x-ray beam by pivoting the x-ray tube results in improved systems for standard radiography, linear tomography, and largescale angiography. In standard radiography and large scale angiography systems, moving primary and secondary slots synchronized with the pivoting of the x-ray tube provide efficient removal of secondary radiation. In linear tomography systems, the object and film are moved synchronously with the pivoting of the x-ray tube, and primary and secondary slots which are stationary remove secondary radiation.
