Dark-field: A new kind of x-ray imaging

该项目旨在开发新的X射线成像能力，通过提取X射线散射产生的暗场，观察物体内部并绘制出那些太小而无法直接看到的细节。 暗场图像可以揭示制造部件中的微小裂缝，在安全检查中发现粉末状爆炸物或毒品，并检测肺部许多微小气囊的大小变化。该项目的预期成果包括新的仪器和分析方法，这将使X射线暗场成像定量和广泛采用。这些方法应该有利于澳大利亚同步加速器的非侵入性多尺度成像，并在工业，安全和医疗保健中装备X射线成像。

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.
