This project aims to develop new x-ray imaging capabilities that look inside an object and map out those details that are too small to be seen directly, by extracting the dark-field which is produced as x-ray light scatters. Dark-field images can reveal tiny cracks in manufactured parts, discover powdered explosives or drugs during security screening, and detect changes in the size of the many tiny air sacs in the lungs. Expected outcomes of this project include new instruments and methods of analysis that will allow x-ray dark-field imaging to be quantitative and widely adopted. These methods should benefit non-invasive multi-scale imaging at the Australian Synchrotron and equip x-ray imaging in industry, security and healthcare.

该项目旨在开发新的X射线成像功能，这些功能可以看到一个物体内部，并通过提取作为X射线光散射的深色场来绘制出太小而直接看到的细节。 暗场图像可以揭示制造零件的微小裂缝，在安全筛查过程中发现粉末状爆炸物或药物，并检测肺中许多微小的空气囊的变化。该项目的预期结果包括新工具和分析方法，这些方法将允许X射线暗场成像进行定量并广泛采用。这些方法应受益于澳大利亚同步器的非侵入性多尺度成像，并在行业，安全和医疗保健中设备X射线成像。
