Exploration and research of high contrast and high resolution two-dimensional x-ray grids

X-ray grids are the core components of medical imaging equipment, which can filter X-ray scattering and thus enhancing image contrast and quality. Utilizing the high-lead-equivalent cladding glass materials with excellent X-ray absorption capabilities and acid-soluble core glass materials, and combined with the microchannel plate preparation process, a twodimensional hollow-core array structure composed of high-lead-equivalent cladding glass materials was obtained, which can effectively improve the contrast and resolution of images during X-ray imaging. The results show that the twodimensional X-ray grids have good absorption of X-ray scattering, reduce fog or haze in images, improve contrast, and have better imaging quality compared with metal X-ray grids for diagnostic images. It provides a new way and support for the preparation of high-performance X-ray grids.
