SINGLE SOURCE DUAL ENERGY HAVING TWO FILTERS FOR X-RAY SPECTRUM DIFFERENTIATION IN THE CASE OF RADIATOR SCREENS HAVING SLOTTED PLATES |
摘要 |
A slotted plate is for limiting an incident x-ray radiation. The slotted plate includes at least one slotted opening and two different x-ray filter regions for x-ray spectrum differentiation of the incident x-ray radiation. The two different x-ray filter regions are permanently arranged in the region of the at least one slotted opening such that radiation portions of the x-ray radiation penetrating the slotted opening having different x-ray spectra can be generated simultaneously. A radiator screen, an x-ray radiator for generating a radiation beam fan, a computer tomography device having such an x-ray radiator, and a method for controlling such a computer tomography device are also disclosed. |

1. A slotted plate for limiting and shaping an X-ray fan beam, comprising:
at least one first slotted opening; and two different X-ray filter regions for X-ray spectrum differentiation of an incident X-ray beam, the two different X-ray filter regions being permanently arranged in a region of the at least one first slotted opening such that radiation components of the X-ray beam penetrating the at least one first slotted opening including different X-ray spectra are simultaneously generatable. |
