The absorbed doses and energy imparted during conventional radiography and tomography of the temporomandibular joint were examined. Absorbed doses from the lateral-oblique transcranial projection and lateral tomography were low (0.02 to 7 mGy). From the axial projection the thyroid gland and salivary glands received a substantial dose (15 to 54 mGy) which was considerably decreased using an improved design of collimator. Radiation to the lens of the eye for the transmaxillary projection and for frontal tomography was 3 to 8 mGy. This can be reduced by a factor of 25 using lead-glass eye shields. The mean energy imparted from a bilateral examination of the temporomandibular joints using axial projection, four exposures for the transcranial lateral-oblique views, two exposures in the transmaxillary projection and lateral tomography views using a multi-film cassette was 34 mJ. The axial projection accounted for 50% of this figure.
对颞下颌关节进行传统放射成像和断层扫描时的吸收剂量及授予能量进行了检测。经颅侧斜位投照和侧位断层扫描的吸收剂量较低（0.02至7毫戈瑞）。轴位投照时，甲状腺和唾液腺接受的剂量较大（15至54毫戈瑞），采用改进设计的准直器后剂量大幅降低。经上颌投照和额部断层扫描时，眼部晶状体接受的辐射剂量为3至8毫戈瑞。使用铅玻璃眼罩可将此剂量降低25倍。采用轴位投照对颞下颌关节进行双侧检查、经颅侧斜位视图进行4次曝光、经上颌投照进行2次曝光以及使用多片暗盒进行侧位断层扫描视图检查时，授予的平均能量为34毫焦。该数值的50%由轴位投照贡献。
