Abstract
Image contrast grids include a body having openings and an x-ray absorbing material in the openings. The openings can be formed by various micromachining techniques and the x-ray absorbing material can be formed in the openings by various coating and deposition techniques. The image contrast grids can have contoured surfaces for improved focusing capabilities. The image contrast grids can remove Compton scattered x-rays in two, non-normal dimensions. The openings can be formed with fine structures that are not visible in most imaging modes.
