  • Collimator, X-ray irradiator, and X-ray apparatus
    Patent number: 7206383
    Abstract: A collimator includes a pair of first plate members which define an X-ray passing aperture by a spacing between their opposed end faces, a second plate member which is movable in a direction parallel to a moving direction of the first plate members, a pair of third plate members which are movable symmetrically with each other in a direction perpendicular to the moving direction of the first plate member and which define an X-ray passing aperture by a spacing between their opposed end faces, and a fourth plate member which is movable in a direction parallel to the moving direction of the third plate members.
