摘要
为了解决医用诊断数字减影血管造影(Digital Subtraction Angiography,DSA)系统性能检测及检测人员操作时不受X射线的辐照,研制了一套改进的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。研究设计了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。试验结果表明,在不加载骨骼模块时,能看到直径为2 mm的动脉模拟血管,同时能分辨直径2 mm的模拟血管上1/2血管大小的血管瘤或栓塞模拟体;加载骨骼体模块后,可以分辨碘浓度为150 mg/cm^3、直径2 mm的模拟动脉;遥控装置遥控距离>50 m,移动速度28 mm/s。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,完全避免了操作时受到X射线的照射。
In order to solve the medical diagnostic digital subtraction angiography(DSA)system performance test and prevent the test personnel operation from affecting by X ray irradiation,the present study developed a set of improved DSA phantom for measuring the performance of the body.Phantom was designed by using organic glass materials processing.Module of mobile radio remote control method was adopted.Phantom of the performance test was conducted on normal DSA system.Plug-ins of organic glass artery simulation module plug-in,skeleton module,contrast linear module and low contrast resolution module were designed.The movement of the modules was controled by remote control device drivers.The experimental results showed that2mm diameter of simulated artery blood vessels without loading the skeleton module could be seen,and a hemangioma or embolization simulation of1/2blood vessels in the simulated vessel with2mm diameter could be distinguished without loading the skeleton module.After loading skeleton module,an iodine concentration of150mg/cm3and a diameter2mm simulated artery could be distinguished.The remote control remote control distance was away from50m,and the movement speed was28mm/s.Conclusion Phantom device is completely in conformity with the requirements of national rules JJG1067-2011Medical Diagnosis Digital Subtraction Angiography(DSA)System X Ray Radiation Source.Application of wireless remote control mobile module can completely avoid the X ray irradiation when operating it.
