Abstract: An X-ray anti-scatter grid having thinner X-ray opaque layers, smaller X-ray opaque diameters, greater aspect ratio, lower weight and improved image resolution is disclosed. A method of forming the X-ray anti-scatter grid is disclosed that includes a set of hollow X-ray transparent glass capillary tubes that are fused together, with an X-ray opaque layer thick enough to block X-rays at a specified energy inside the capillary tubes. The capillary tubes provide the high aspect ratio and light weight, while the X-ray opaque layer is provided by a deposition process that has features similar to atomic layer deposition (ALD). The high aspect ratio and thin layers improves resolution and decreases image artifacts, and large area X-ray anti-scatter grids are provided by aligning the axis of the an X-ray opaque layers to the X-ray source.
