AI中文摘要：
在澳大利亚同步加速器的成像与医学光束线（IMBL）上，进行了多次基于传播和基于分析器的X射线相衬成像实验，成像物体与探测器之间的距离超过100米。这些实验旨在表征IMBL上可能的相衬成像设置。在不同成像场景中，定量评估了光束发散度、多色性和X射线源尺寸对图像对比度和空间分辨率的影响。这项工作的结果将用于改进光束线上现有的成像能力并开发新的成像能力。文中还简要讨论了X射线相衬断层扫描在生物医学样本中的应用，特别是用于医学乳腺癌成像。
英文摘要：
Several propagation-based and analyser-based X-ray phase-contrast imaging experiments with over 100 m between the imaged objects and the detector were carried out at the Imaging and Medical beamline (IMBL) of the Australian Synchrotron. These experiments were aimed at characterization of possible phase-contrast imaging setups at IMBL. Effects of the beam divergence, polychromaticity and X-ray source size on the contrast and spatial resolution of images were evaluated quantitatively in different imaging scenarios. The results of this work will be used for improving the existing and developing new imaging capabilities at the beamline. Applications to X-ray phase-contrast tomography of biomedical samples, particularly for medical breast cancer imaging, are briefly discussed.
