Absorbed doses in organs of special interest from lateral cephalography were measured by thermoluminescence dosimetry in a tissue equivalent phantom head. The radiographic examination was performed in a standardized manner by using a carefully collimated radiation field and a near-focus dodger. The actual tube voltages ranged from 63-127 kVp. The absorbed dose was described as a function of tube voltage. In all measurement sites the absorbed dose decreased with increasing tube voltage. This reduction was most obvious in the low tube voltage range. From the results a lowest recommendable tube voltage was given for the different measurement sites varying from approximately 75 kVp (thyroid region) to approximately 100 kVp (parotid region). A high tube voltage was found to be important for a low absorbed dose in different organs in lateral cephalography.
通过热释光剂量测定法，在组织等效体模头部中测量了侧位头颅摄影中特殊感兴趣器官的吸收剂量。通过使用精心准直的辐射场和近焦点遮光器，以标准化方式进行射线照相检查。实际管电压范围为63 - 127 kVp。吸收剂量被描述为管电压的函数。在所有测量部位，吸收剂量随管电压升高而降低。这种降低在低管电压范围内最为明显。根据结果，针对不同测量部位给出了最低推荐管电压，范围从约75 kVp（甲状腺区域）到约100 kVp（腮腺区域）。发现高管电压对于侧位头颅摄影中不同器官的低吸收剂量很重要。
