Abstract
An x-ray beam hardening filter and method for making the same is disclosed. According to an embodiment, the method comprises etching a plurality of regularly spaced pits into a surface area of a sheet having an x-ray beam hardening quality, aligning the sheet to a support member and bonding the sheet to the support member. An x-ray beam hardening filter can be made and used which is not only compact and useful in diagnostic x-ray imaging, but which is capable of shaping an x-ray energy spectrum envelope in a highly controllable manner.
