Measurements of skin doses during radiography in scoliosis have been performed with a.p. and p.a. direction of the beam. In order to keep the doses to the patients low, high kV, a film-focus distance of at least 3 m, a fast screen-film combination, lead shielding, a collimator with rotating compensating filter, and a grid of the moving anti-scatter type are recommended. By using the p.a. direction the dose to the breast is reduced by a factor in the range of 88 to 97 per cent. Further dose reduction might be achieved by removal of the anti-scatter grid and use of the air gap technique. Relinquishment of the radiographic principle of bringing the object to be examined as near the film as possible did not reduce the diagnostic information.
在脊柱侧弯放射摄影期间，已在前后位和后前位束方向上进行了皮肤剂量测量。为了使患者的剂量保持在低水平，建议采用高千伏、至少3米的焦片距、快速增感屏-胶片组合、铅屏蔽、带有旋转补偿滤过器的准直器以及移动反散射型滤线栅。通过使用后前位方向，乳房所受剂量可降低88%至97%。通过移除反散射滤线栅并使用空气间隙技术，可能会进一步降低剂量。放弃将待检查物体尽可能靠近胶片的放射摄影原则并不会减少诊断信息。
