在这封信中,我们提出了一个单步方法,同时检索X射线吸收和相位图像有效的成像能量和材料特性的广泛范围。我们的方法依赖于光谱分辨强度测量的可用性,这是现在可能使用半导体X射线光子计数探测器。新的检索方法的推导和结果显示出良好的一致性。
In this letter we present a single-step method to simultaneously retrieve x-ray absorption and phase images valid for a broad range of imaging energies and material properties. Our method relies on the availability of spectrally resolved intensity measurements, which is now possible using semiconductor x-ray photon counting detectors. The new retrieval method is derived and presented with results showing good agreement.
