Abstract
An x-ray apparatus that accepts an x-ray radiator therein has shielding for the x-ray leakage radiation originating from the x-ray radiator that is an Integral component of (built into) the x-ray apparatus. An x-ray radiator with an x-ray tube and a housing in which the x-ray tube is contained is composed only of materials that are not suitable for absorption of x-rays.
Claims6
An x-ray computed tomography apparatus comprising:
- a computed tomography scanner having an opening therein adapted to receive an examination subject;
- a gantry rotatably mounted in said scanner for rotation around said opening;
- an unshielded x-ray radiator mounted at said gantry, said unshielded x-ray radiator comprising a cathode and an anode contained in a tube, and a radiator housing containing said tube, said radiator housing being comprised of material that is non-shielding for x-rays, said unshielded x-ray radiator emitting diagnostic x-ray radiation and x-ray leakage radiation by operation of said cathode and said anode in said tube in said radiator housing;
- shielding for said x-ray leakage radiation built into said gantry and conforming at least in part to said radiator housing of said unshielded x-ray radiator to shield against emergence beyond said shielding of said x-ray leakage radiation emitted by said unshielded x-ray radiator, said unshielded x-ray radiator, said shielding and said gantry all being co-rotatable around said opening;
- and
- a mounting that mounts said radiator housing in said gantry allowing removal of said x-ray radiator, as a unit, with said shielding remaining built into said gantry.
