在钡灌肠和结肠气钡双重造影中均有大量放射线照射性腺区,而受检查者常为育龄妇女,因此用一种适宜的方法测定由上述X线检查卵巢接受的射线量是非常重要的。作者介绍了一种在钡灌肠时将热光剂量仪(TLDs)置于灌肠管末端以测定卵巢射线量的方法。由于插入直肠内的灌肠管末端正好在双侧卵巢所在平面的中点,检查过程中当双侧卵巢受直接照射如拍全腹片时,TLDs也在直射之下;当在肝脾曲或回盲部点片时,卵巢和TLDs均不受照 In both barium enema and colon barium double radiography have a large number of radioactive gonadal area, and the subjects are often women of childbearing age, so using a suitable method to determine by the X-ray examination of the amount of radiation the ovary is very important. The authors describe a method for measuring the amount of ovarian rays by placing thermo-optic dosimeters (TLDs) at the ends of the enema during barium enema. Because the end of the enema inserted into the rectum is exactly at the midpoint of the plane where both ovaries are located, TLDs are also under direct examination during the examination when both ovaries are exposed to direct radiation, for example, Blind spot film, the ovaries and TLDs are not exposed
