| 摘要 |
The present invention relates to a collimator, which can form various radiation penetration areas with various shapes, locations, and numbers through a sliding of shielding plates by mounting the shielding plates on a support frame to allow the sliding of the shielding plates on the same plane; can form at least one radiation penetration area by laminating collimator modules in which the shielding plates are combined with the support frame in a row and changing the arrangement of the shielding plates against the collimator modules; and can independently control each radiation dose toward the radiation irradiation area of an object corresponding to the radiation penetration area. |
