Abstract
A design and performance test of an antiscattering X-ray grid that is based on photosensitive glass was conducted using MCNP simulation. The simulation was designed in three parts: source, scatterer, and grid. The source was a cone type with a single energy of 50 keV, and the scatterer was designed as a box with elemental composition and density the same as those of a human body. Three types of grid were tested: ideal, injection, and electroplating. The ideal-type grid was generally known and contained only a shielding wall, the injection-type grid had the shielding material injected into the glass, and the electroplating-type grid had the shielding material electroplated on the glass lattice skeleton. The ideal-type grid showed a scattered and primary photon ratio (SPR) of 0.106, and the nongrid type showed an SPR of 0.159. The injection-type grid had an SPR of 0.126, which corresponded to 119.3% of that of the ideal type. The electroplating-type grid had an SPR of 0.0964, which corresponded to 93.7% of that of the ideal type. It was understood that the electroplating-type grid showed the most effective reduction of the scattered photons in terms of SPR.
