【摘要】：为解决医用诊断数字减影血管造影(DSA)系统性能检测及检测人员操作时不受X射线的辐照,研制一套改进的DSA计量性能体模装置。体模的设计采用有机玻璃材料进行加工;模块的移动采用无线电信号遥控的方法;体模的性能试验在正常状态的DSA系统上进行。研究设计有机玻璃动脉模拟模块插件、骨骼模块插件、对比度线性模块插件和低对比度分辨力模块插件;模块的移动利用遥控驱动装置。试验得到:在不加载骨骼模块时,能看到直径为1mm的动脉模拟血管,同时能分辨直径2mm的模拟血管上1/2血管大小的血管瘤或栓塞;加载骨骼体模块后,可以分辨碘浓度为150mg/cm3、直径2mm的模拟动脉;遥控装置遥控距离50m,移动速度28mm/s。结果表明:体模装置完全符合国家规程JJG 1067——2011《医用诊断数字减影血管造影(DSA)系统X射线辐射源》要求;应用无线电遥控移动模块插件,避免操作时受到X射线的照射。
[Abstract]:In order to solve the problem that the performance of medical diagnostic digital subtraction angiography (DSAs) system is not irradiated by X-ray, an improved DSA measurement performance phantom device is developed.The design of phantom is made of plexiglass material, the mobile module is remote-controlled by radio signal, and the performance test of phantom is carried out on the normal DSA system.Research and design of plexiglass artery simulation module plug-in, skeleton module plug-in, contrast linear module plug-in and low contrast resolution module plug-in; module mobile use remote driving device.The results showed that when the bone module was not loaded, the artery with diameter of 1mm could be seen as a mimic vessel, and at the same time, the hemangioma or embolism of the simulated vessel with diameter 2mm could be distinguished by a one-second of the size of the vessel; after loading the module of the skeleton body,The simulated arteries with an iodine concentration of 150 mg / cm ~ 3, diameter 2mm, remote control distance of 50 m and moving speed of 28 mm / s can be identified.The results show that the device fully meets the requirements of JJG 1067-2011 "X-ray radiation source" in the medical diagnostic digital subtraction angiography (DSA) system, and the radio-remote control module plug-in is used to avoid exposure to X-ray during operation.
