| 摘 要： | 目的:采用屏蔽防护法屏蔽和降低乳腺X射线摄影中散射辐射对受检者甲状腺及乳腺所致辐射剂量的方法,并对其采用防护措施的防护效果进行试验研究。方法:在数字化乳腺X射线摄影(DR)中,随机选取30例乳腺X射线受检者,采用本中心新研制的0.5 mm Pb铅橡胶甲状腺-乳腺防护衣对受检者进行屏蔽。采集数据方法:在防护衣内侧和外侧分别各放置一组LiF(Mg·Cu·P)热释光剂量探测器,在同一检测条件下进行照射后,分别测量甲状腺-乳腺防护衣内侧和外侧两组入射空气比释动能数值。结果:防护衣内外入射空气比释动能的差异具有统计学意义(P<0.05)。防护衣对甲状腺的防护效率为(99.25±0.99)%,对侧乳腺的防护效率为(99.17±1.03)%。结论:甲状腺-乳腺防护衣可以降低甲状腺和乳腺在X射线摄影时的散射辐射,并且屏蔽防护效果显著。
