Abstract: A grating assembly (G0-G2) for interferometric X-ray imaging. The assembly (GA) comprises a carrier sheet (CS) having deposited thereon grating tiles (GT), the said sheet having edge portions (E1-E4) and a thermal expansion coefficient. Distinct from the sheet, there are stabilizer bar members (S1-S4) affixed along respective ones of the said edge portions, the stabilizer bar members having substantially the same thermal expansion coefficient as the said sheet.
