摘　　要：通过颅面部X线摄影专用铅遮线板研制与应用,,缩小照射野面积,提高图像质量,减少受检者的接受辐射剂量。文章依据颅面部X线摄影的几何形状,设计了3种照射野尺寸的铅遮线板和6种图像布局。实验结果表明：颅面部X线摄影照射野面积平均减少41.3%~85.3%;X线照片图像清晰,号码标记规范。从而得出如下结论：使用颅面部X线摄影专用铅遮线板,缩小了照射野面积,显著提高了图像质量,同时有效地降低了受检者的辐射剂量。Lead shields with three illuminating areas and six kinds of image layout were designed according to the geometry of craniofacial radiograph.The test results showed that field size of craniofacial radiography was reduced by 41.3%~85.3% on average.Clear radiographic images and standard numeric markers were obtained.The radiation dose to physical examinees was effectively decreased.
