视频透视吞咽研究(VFSS)是一种公认的标准诊断成像技术，用于研究吞咽障碍和吞咽困难。患者在坐在椅子或轮椅上的姿势下接受评估。使用X光透视，根据医生的指示通过饮食检查患者的吞咽状态。VFSS程序延长，VFSS工作人员暴露在辐射中。因此，我们评估了原始的铅屏蔽装置(Olsd)，它可以安装在桌子的扶手上并垂直放置。OLSD的铅当量厚度为0.3mmPb，重量约为600万公斤，尺寸为50厘米 × 50厘米 × 8.0亿毫米。我们使用了一个人体体模和一个辐射测量仪，在医生和医务人员的位置上，在离地面150厘米的高度(即眼睛的水晶晶状体的高度)，有和没有受到散射辐射的保护。在测量了散射辐射后，我们创建了使用和不使用olsd的辐射地图。无OSD和有OSD时医生体位的剂量率分别为190µSv/h和92µSv/h，使用OSD后剂量减少率为51.6%。此外，辐射地图还增加了散射辐射分布的清晰度。这样的信息应该使人们对医生和其他医务人员的暴露有更大的认识。因此，在透视期间，OLSD有效地提供了对医生位置的散射辐射的保护。这可能有助于减少VFSS工作人员的风险。
The videofluoroscopic swallowing study (VFSS) is a recognized standard diagnostic imaging technique that is used to investigate swallowing disorders and dysphagia. Patients were assessed in a seated posture on a chair or wheelchair. Using X-ray fluoroscopy, the state of patients’ swallowing was checked by eating and drinking according to the physician's instructions. VFSS procedures are prolonged, and VFSS staff members are exposed to radiation. Therefore, we evaluated original lead shielding device (OLSD) that can be attached to the handrail of a table and placed vertically. The OLSD has a lead-equivalent thickness of 0.3 mmPb, weighs about 6 kg, and has the dimensions 50 cm × 50 cm × 8.0 mm. We used a human phantom and a radiation survey meter with and without protection from scattered radiation at the positions of the physician and medical staff at the height of 150 cm above the floor (i.e., the height of the eye’s crystalline lens). After measuring the scattered radiation, we created radiation maps with and without the OLSD. The dose rate at the physician’s position without and with the OLSD was 190 µSv/h and 92 µSv/h, respectively, and a dose reduction of 51.6% with the plate. Moreover, the radiation maps added clarity to the distribution of the scattered radiation. Such information should lead to greater awareness about exposures to physicians and other medical staff. Thus, the OLSD effectively provided protection from scattered radiation at the physician’s position during fluoroscopy. It may contribute to the reduction of staff exposure for VFSS.
