H&D 曲线是针对暴露于 60Co、4-MV 和 45-MV 光子的各种胶片/屏幕组合获得的。数据表明，发光屏幕比铅屏幕或直接曝光更能增强对比度。柔性胶片盒对患者来说更舒适，超大胶片可用于较大的患者。
H & D curves were obtained for various film/screen combinations exposed to 60Co, 4-MV, and 45-MV photons. Data indicate that contrast is enhanced more by light-emitting screens than by lead screens or direct exposure. Flexible film cassettes are more comfortable for the patient, and extra-large film can be used for larger patients.
