Interferometer grating support for grating-based x-ray imaging and/or a support bracket therefor

摘要

An interferometer grating support (118) of an imaging system (100) configured for grating-based x-ray imaging includes at least two elongate supports (302) separated from each other by a non-zero distance, wherein the at least two elongate supports have a first end (312) and a second end (316). The grating support further includes a first arc shaped grating (202) affixed to the first end and a second arc shaped grating (204) affixed to a second end (316). A non-transitory computer readable medium is configured with computer executable instructions which when executed by a processor of a computer cause the processor to: move a grating support, which supports G0 and G1 gratings of an interferometer and a bowtie filter, into a region between a low energy photon filter and a beam collimator, which are between a radiation source and an examination region, for a grating-based x-ray imaging scan.
