The results of a survey of doses imparted on 41 patients undergoing hysterosalpingography is presented. Dosimetric evaluations were carried out by measuring both the dose-area product using a transmission ionization type chamber, and the entrance surface dose using thermoluminiscent dosimeters. As a result, a local reference dose value was obtained for this examination. Correlations between the dose-area product and the entrance surface dose data were analysed and compared in order to find the most appropriate dosimetric procedure. The median dose-area product obtained was 713 cGy cm2 (range 247 cGy cm2-1623 cGy cm2). Ovarian doses were also calculated, and a median value of 4.6 mGy was obtained for the whole examination. Effective doses were estimated with a median value of 3.1 mSv, and a range of 1.0 mSv-8.1 mSv.
本文展示了对41名接受子宫输卵管造影术患者的剂量调查结果。通过使用透射电离型腔室测量剂量面积乘积以及使用热释光剂量计测量体表入射剂量来进行剂量学评估。结果，获得了该检查的局部参考剂量值。分析并比较了剂量面积乘积与体表入射剂量数据之间的相关性，以找到最合适的剂量学程序。获得的剂量面积乘积中位数为713 cGy cm²（范围为247 cGy cm² - 1623 cGy cm²）。还计算了卵巢剂量，整个检查的中位数为4.6 mGy。有效剂量估计中位数为3.1 mSv，范围为1.0 mSv - 8.1 mSv。
