The absorbed doses and energy imparted in lateral and antero-posterior tomography of the teeth and jaws were measured. A multi-film cassette with 5 films was exposed using a diameter of the circular collimator of 1.5 cm. With one exception, the absorbed doses were below 1 mGy. The parotid gland towards the roentgen tube received about 2 mGy in lateral tomography of the mandibular third molar. The energy imparted in lateral tomography was 0.6 mJ and in antero-posterior tomography about 2.5 mJ. Since the radiation doses in tomography of the teeth and jaws were low compared with estimated risk levels, they should not deter from using tomography.
测量了牙齿和颌骨的侧位及前后位断层扫描中的吸收剂量和授予能量。使用直径为1.5厘米的圆形准直器，对装有5张胶片的多层暗盒进行曝光。除了一个例外情况，吸收剂量均低于1毫戈瑞。在下颌第三磨牙的侧位断层扫描中，朝向X射线管的腮腺接受了约2毫戈瑞的剂量。侧位断层扫描中授予的能量为0.6毫焦，前后位断层扫描中约为2.5毫焦。由于牙齿和颌骨断层扫描中的辐射剂量与估计的风险水平相比很低，因此不应妨碍使用断层扫描。
