Abstract

Monte Carlo methods have been used to evaluate the performance of x-ray grids in radiography, quantitatively. To correspond with practical arrangements in radiography, the simulations have been done in the condition of the polyenergetic cone-beam geometry and the focused grid. The scatter intensities relative to the primary intensities were calculated for various values of object thickness, field size, tube voltage, and grid ratio. The Bucky factor, contrast improvement factor, and selectivity were used for comparison of the performance of the grid. The results of the calculations are in good agreement with the limited experimental data available. This calculation result is useful for the development of optimal antiscatter grids and selection of the suitable grid in radiographic procedures.
