Multi-modal hard x-ray imaging sensitive to absorption, refraction, phase and scattering contrast is demonstrated using a simple setup implemented with a laboratory source. The method is based on selective reflection at the edge of a mirror, aligned to partially reflect a pencil x-ray beam after its interaction with a sample. Quantitative scattering contrast from a test sample is experimentally demonstrated using this method. Multi-modal imaging of a house fly (Musca domestica) is shown as proof of principle of the technique for biological samples.
利用实验室光源实现的简单装置展示了对吸收、折射、相位和散射对比度敏感的多模态硬X射线成像。该方法基于镜子边缘的选择性反射，镜子经校准后能在铅笔状X射线束与样品相互作用后对其进行部分反射。使用该方法通过实验证明了测试样品的定量散射对比度。展示了家蝇（Musca domestica）的多模态成像，作为该技术用于生物样品的原理证明。
