Abstract
A method for assembling an adjustable collimator for spatially fractionated radiation therapy is disclosed. Penetrating sheets that can transmit rays are stacked to form penetration sections, and the quantity of penetrating sheets is calculated. The thickness of each penetration section corresponds to the width of each radiation area. Shielding sheets that can block rays are stacked to form shielding sections, and the quantity of shielding sheets is calculated, with the thickness of each shielding section corresponding to the spacing between the radiation areas. The penetration sections and shielding sections form a collimation module, with shielding sections on opposite sides. Penetration and shielding sections of different thicknesses are assembled based on the radiation range and the radiation area spacing. Since the thickness of the penetration and shielding sections can be adjusted as needed, it can be applied to spatially fractionated radiation therapy with different requirements, achieving cost reduction.
