SLIT RADIOGRAPHY DEVICE PROVIDED WITH ABSORPTION ELEMENTS, AND PROCEDURE FOR PRODUCING ABSORPTION ELEMENTS |
摘要 |
A slit radiography device scans a body under examination with a fan shaped X-ray beam. A number of absorption elements placed next to each other can be moved into the X-ray beam to a greater or lesser extent in order to influence the X-ray radiation incident on the body per sector of the X-ray beam. As seen in the longitudinal direction of the slit the absorption elements are designed such that a certain distance is present between them. As seen in the direction of the X-ray radiation the thickness of the material of the absorption elements is always the same, i.e. there are no gaps between the absorption elements that the X-ray radiation can shine through. |
