摘要:
A method is disclosed for producing projective and tomographic phase contrast images of an examination object, preferably a patient, with the aid of an X-ray system, and a corresponding X-ray system for carrying out this method. In at least one embodiment of the method, X-ray optical grating sets tuned to different energy ranges are used to determine energy-dependent phase shifts upon penetration of an examination object, a difference value is formed from these energy-dependent phase shifts, and tomographic or projective images are produced therefrom.

公开了一种借助于X射线系统产生检查对象,优选患者的投影和断层相位对比图像的方法以及用于执行该方法的相应X射线系统。 在该方法的至少一个实施例中,调整到不同能量范围的X射线光栅设置用于在检查对象穿透时确定依赖于能量的相移,由这些依赖于能量的相移形成差值, 从其产生断层图像或投影图像。
