NARROW BAND X-RAY SYSTEM AND FABRICATION METHOD THEREOF

摘要

A narrow band x-ray filter can include: a substrate; and a sheaf of one or more reflection units stacked upon each other on the substrate. Each reflection unit can include: a first set of at least two discrete spacers on a respective underlying structures, a reflector disposed on the first set of spacers so as to form a void between the respective underlying structure and the reflector; and a first set of at least two discrete shims disposed on th e first set of at least two spacers, each shim being at least substantially th e same thickness as the reflector. A first device to produce a narrow band x-r ay beam may include such a filter or an x-ray telescope. A second device to mak e an x-ray image of a subject may include the first device.
