Preparation method of scintillation crystal array uniformly integrated with tungsten sheets

The invention relates to a preparation method of a scintillation crystal array uniformly integrated with tungsten sheets, and the method comprises the following steps: obtaining a shaping mold in advance, the shaping mold is provided with a plurality of vertical crystal strip accommodating cavities arranged in an array, and the upper and lower ends of each crystal strip accommodating cavity are open; the shaping mold is placed on a horizontal bottom plate; crystal strips are inserted into all the crystal strip containing cavities one by one, the crystal strips are fixed into the corresponding crystal strip containing cavities through adhesives, and the four side faces and the upper surface of each crystal strip are each coated with a reflecting layer; and after curing and forming, unneeded parts of the bottom plate and the shaping mold are removed, the left part of the shaping mold serves as a constituent part of the scintillation crystal array and is made of a tungsten material, and meanwhile the wall thickn
