Shaped filters that are constructed of lead-loaded acrylic material for use in patient radiography are discussed. Use of the filters will result in improved overall image quality with significant exposure reduction to the patient (approximately a 2X reduction in breast exposure and a 3X reduction in thyroid gland exposure). Detailed drawings of the shaped filters for scoliosis radiography, cervical spine radiography, and for long film changers in special procedures are provided. The use of the scoliosis filters is detailed and includes phantom and patient radiographs and dose reduction information.
讨论了用于患者放射成像的由含铅丙烯酸材料制成的成形滤线器。使用这些滤线器将提高整体图像质量，并显著减少患者的辐射暴露（乳房暴露减少约2倍，甲状腺暴露减少约3倍）。提供了用于脊柱侧弯放射成像、颈椎放射成像以及特殊检查中长片换片机的成形滤线器的详细图纸。详细介绍了脊柱侧弯滤线器的使用情况，包括体模和患者的X光片以及剂量减少信息。
