    • In a method for examining a body region executing a periodic motion in an examination subject with a diagnostic apparatus having a radiation source for generating radiation penetrating the examination subject and a detector system for the radiation emanating from the radiation source, the intensity of the radiation emanating from the radiation source is modulated between a reference value and a reduced value compared to the reference value, substantially synchronously with the movement, so that the reference value is present during a phase of the periodic motion to be imaged with the diagnostic apparatus, and substantially only the data that were output by the detector system during the presence of the reference value of the radiation are utilized for the determination of the image.
    • 在利用具有用于产生穿过检查对象的辐射源的辐射源的诊断装置和用于从辐射源发出的辐射的检测器系统来检查检查对象中执行周期性运动的身体区域的方法中,辐射发射的强度 与基准值相比,辐射源在与基准值相比基准值和减小的值之间进行调制,与移动基本上同步,使得参考值在与诊断装置成像的周期性运动的相位期间存在, 仅在辐射的参考值存在期间由检测器系统输出的数据被用于图像的确定。
