Using very small photoluminescence glass dosimeters (PLDs), we have evaluated entrance skin dose (ESD) during neuron-interventional radiology (NIVR) procedures in both patients and operators. Also we tried to make a prototype of x-ray protection device during NIVR procedures.Subjects in this research are 32 patients (11 male and 22 female ; median age:61.5 years ; age range:15-76 years). ESD on Operators have bean measured simultaneously. As angiographic parameters, x-ray tube voltage, total exposure time, total fluoroscopic time, the number of digital subtraction angiography (DSA) studies and frames and dose-area product (DAP) were recorded during NIVR procedure.As a result, total mean of x-ray tube voltage was 77.4 kV±8.6 (standard deviation) ; posterior-anterior plane, 79.1 kV±8.6;lateral plane,74.0 kV±7.4. Patient's maximal total mean ESD was 1004 mGy±1295 per procedure at right temporal area. Thus, we developed a cap-type ware to measure ESD of the head and neck easily, and made a patent application. In addition, we have developed a prototype of x-ray protection device during NIVR procedures, and made another patent application.Monitoring patient's ESD and its distribution by our procedure is useful to reduce radiation exposure and prevent patients from radiation injury in NIVR procedures.

使用非常小的光致发光玻璃剂量计（PLD），我们在患者和操作员的神经间距放射学（NIVR）程序中评估了入口皮肤剂量（ESD）。同样，我们在NIVR程序期间尝试制作X射线保护装置的原型。这项研究中的主题是32例患者（11名男性和22名女性；中位年龄：61.5岁；年龄范围：15-76岁）。运算符的ESD豆的测量类似。在NIVR过程中记录了血管造影参数，X射线管电压，总暴露时间，总透视时间，数字减法血管造影研究（DSA）研究（DSA）研究（DSA）研究（DSA）研究（DSA）和框架和剂量区域产品（DAP）。后侧面，79.1 kV±8.6;横向平面，74.0 kV±7.4。在右临时区域，患者的最大总ESD为每次手术1004 MGY±1295。那就开发了一种盖型器皿，以轻松测量头部和颈部的ESD，并进行了专利应用。此外，我们在NIVR过程中开发了X射线保护装置的原型，并进行了另一种专利应用。对患者的ESD及其通过我们的程序进行分配对于减少辐射暴露和防止NIVR程序中的患者辐射受伤很有用。
