A Multilayer Mirror/Monochromator for Dual-Energy Digital Subtraction Angiography

将设计和制造一对大型多层反射器，一个在碘的K边缘上方工作，另一个在碘的K边缘下方工作，用于使用同步辐射的双能减影血管造影术。在这个II期项目中，将测量k边缘的镜面响应，并在同步加速器血管造影波束线中分析其性能。为了优化反射率，将对制造参数进行进一步的研究。

A pair of large multilayer reflectors will be designed and fabricated, one to operate just above, and one just below the K- edge of iodine for application to dual-energy subtraction angiography using synchrotron radiation. The specular-angular responses at the K-edge will be measured, and the performance will be analyzed in a synchrotron angiography beam line, in this Phase II program. Additional studies of fabrication parameters will be carried out with a view of optimizing reflectivity.
