钨功能纸（TFP）含有 80% 重量的钨，具有辐射屏蔽性能。我们研究了 TFP 在介入或治疗性血管造影过程中保护操作人员的用途。使用水当量体模和固定 C 臂透视检查，在有或没有 TFP 的情况下测量模拟患者散射辐射的空气比释动能率。使用不同数量的 TFP 片进行屏蔽，在操作员的眼睛、胸部、腰部和膝盖处进行测量。还利用蒙特卡罗模拟来分析有和没有 TFP 屏蔽时所传递的剂量率。在电影模式下，当TFP片的数量变化为1、2、3、5和10时，相对于无TFP屏蔽的空气比释动能率分别降低如下：在眼睛水平处，24.9%、29.9%、41.6%、50.4%和56.2%；胸部水平：25.3%、33.1%、34.9%、46.1% 和 44.3%；在腰部水平，45.1%、57.0%、64.4%、70.7%和75.2%；在膝盖处，分别为 2.1%、2.2%、2.1%、2.1% 和 2.1%。在透视模式下，相对于无 TFP 屏蔽，空气比释动率分别降低如下：在眼睛水平处，24.8%、30.3%、34.8%、51.1% 和 58.5%；胸部水平：25.8%、33.4%、35.5%、45.2% 和 44.4%；腰部水平分别为 44.6%、56.8%、64.7%、71.7% 和 77.2%；在膝盖处，分别为 2.2%、0.0%、2.2%、2.8% 和 2.5%。 TFP纸对临床环境中遇到的散射辐射表现出良好的辐射屏蔽性能，并且被证明在减少介入放射学期间操作者的辐射暴露方面具有潜在的应用。
Tungsten functional paper (TFP), which contains 80% tungsten by weight, has radiation‐shielding properties. We investigated the use of TFP for the protection of operators during interventional or therapeutic angiography. The air kerma rate of scattered radiation from a simulated patient was measured, with and without TFP, using a water‐equivalent phantom and fixed C‐arm fluoroscopy. Measurements were taken at the level of the operator's eye, chest, waist, and knee, with a variable number of TFP sheets used for shielding. A Monte Carlo simulation was also utilized to analyze the dose rate delivered with and without the TFP shielding. In cine mode, when the number of TFP sheets was varied through 1, 2, 3, 5, and 10, the respective reduction in the air kerma rate relative to no TFP shielding was as follows: at eye level, 24.9%, 29.9%, 41.6%, 50.4%, and 56.2%; at chest level, 25.3%, 33.1%, 34.9%, 46.1%, and 44.3%; at waist level, 45.1%, 57.0%, 64.4%, 70.7%, and 75.2%; and at knee level, 2.1%, 2.2%, 2.1%, 2.1%, and 2.1%. In fluoroscopy mode, the respective reduction in the air kerma rate relative to no TFP shielding was as follows: at eye level, 24.8%, 30.3%, 34.8%, 51.1%, and 58.5%; at chest level, 25.8%, 33.4%, 35.5%, 45.2%, and 44.4%; at waist level, 44.6%, 56.8%, 64.7%, 71.7%, and 77.2%; and at knee level, 2.2%, 0.0%, 2.2%, 2.8%, and 2.5%. The TFP paper exhibited good radiation‐shielding properties against the scattered radiation encountered in clinical settings, and was shown to have potential application in decreasing the radiation exposure to the operator during interventional radiology.
