中文摘要 | 牙科全口牙攝影及牙科電腦斷層已經成為診斷及治療牙齒疾病不可或缺的檢查。依據合理抑低(ALARA)的原則,牙科醫師需要有高品質的的X光影像且盡可能的降低病人的輻射劑量。本研究評估牙科電腦斷層時頭頸部器官之輻射劑量及健康效應。使用光激發光劑量計(optically stimulated luminescent dosimeter, OSLD)計算牙科電腦斷層掃描之各器官有效劑量。腦、骨表面、皮膚、唾液腺、紅骨髓、甲狀腺、食道有效劑量分別為0.0018、0.0562、0.4702、0.2792、1.7193、0.3504、0.1597 (mSv),其中以紅骨髓的有效劑量最高;水晶體等價劑量為3.75 mSv。根據ICRP報告之健康效應風險計算,結果顯示牙科電腦斷層之機率效應風險為5.011×10^(-5)。 |
英文摘要 | Dental panoramic x-ray and Dental CT have become a part of disease diagnosis and treatment of teeth checks. Based low as reasonably achievable (ALARA) principle, doctors need to have a high-quality X-ray images and as much as possible to reduce the radiation dose. This study is radiation dose measurement and health effect assessment on head and neck with dental computed tomography. Optically Stimulated Luminescence Dosimeter (OSLD) calculate effective dose with Dental CT. Brain, bone surface, skin, salivary glands, red bone marrow, thyroid, esophagus effective dose were 0.0018, 0.0562, 0.4702, 0.2792, 1.7193, 0.3504, 0.1597 (mSv). Among red bone marrow has the highest effective dose; crystalline lens equivalent dose was 3.75 mSv. According to the risk assessment health effects of ICRP report, the results showed that the probability of the risk effects of dental CT is 5.011x10^(-5). |
