摘要： A collimator device has at least one masking device that is adjustable between two end positions for collimation of a beam fan in an x-ray CT device, wherein the x-ray fan is schematically not masked in a first end position. The x-ray beam is more than half-masked in a second end position of the masking device. In a method for operation of such a collimator device as well as an x-ray CT device for examination of a subject having an x-ray source, a collimator device, and a control device for regulation of the aperture width of the masking device, an x-ray detector is arranged opposite the x-ray source and the collimator device and that detects the x-rays modified due to the intervening examination subject; and an image construction device reconstructs an image of the examination subject therefrom.
摘要翻译：准直器装置具有至少一个可在两个端部位置之间调节的掩模装置，用于准直X射线CT装置中的束扇，其中，X射线风扇在第一端部位置中未示意地未被遮蔽。在掩蔽装置的第二端位置，X射线束大于半掩模。在这种准直器装置的操作方法以及用于检查具有x射线源的对象的X射线CT装置，准直器装置和用于调节掩蔽装置的孔径宽度的控制装置中， X射线检测器布置在x射线源和准直器装置的对面，并且检测由于介入检查对象而修改的x射线; 并且图像构造装置从其重建检查对象的图像。
