Grating microfabrication for multimodal x-ray imaging


EMSL Project ID
43790

Abstract

We propose to use the new microfabrication capabilities at EMSL to fabricate x-ray optics elements (gratings) for phase contrast x-ray imaging. Phase contrast x-ray imaging is a promising new technique for producing multimodal x-ray images; the additional contrast mechanisms may allow for improvements in medical imaging, biological specimens, materials science, and explosives detection. PNNL has an on-site phase contrast capability, but the difficult fabrication of the high aspect ratio gratings limits both data quality and system design. By working closely with EMSL staff to improve fabrication, we will be able to produce publication-quality x-ray data for a wide range of applications. Additionally, this work will test the capabilities of EMSL's new microfabrication equipment.
