摘要
数字减影血管造影(Digital Subtraction Angiography,DSA)在更换数字减影图像工作站后,需要重新设计高压触发控制和高压控制接口电路。本文通过对数字减影血管造影系统的主机电路及图像工作站的控制电路原理的阐述,对接口电路的设计提供了详实方案,设计出相应的硬件接口电路,进一步解决高压控制信号转换问题,控制产生合适的X射线,以实现新的DSA系统控制正常曝光及图像的采集处理。以上设计,为生物医学工程专业本专科学生的理论学习与实践动手能力相结合提供良好借鉴。
When the digital subtraction angiography(DSA)is changed in the PACS room,the high-voltage trigger controlled andthe high pressure controlled interface circuit are usually needed to be redesigned.To solve the problem of high pressure controlledsignal conversion,and control the generation of suitable X-ray to realize the new DSA system control normal exposure and imageprocessing,the present study provided a detailed design of interface circuit and designed the corresponding hardware interface circuitbased on explaining the principle of the control circuit through the host circuit and PACS room for DSA.Through the above design,it can provide a good reference for the theoretical study and practical ability of the students of biomedical engineering.
