An investigation of a newly devised DSA system consisted of a cooled CCD camera has been made from 1997 to 2000. Since the cooled CCD camera has markedly high contrast resolution, we have considered that the new system should be competent for IV-DSA. The DSA system had been constructed at first, which consisted of X-ray generator, optical unit and digital processing unit. Then the capability of the system for imaging bad been tested. According to the result of the practice examination using artificial blood vessel, we judged the contrast resolution of the image detected by our new system was better than that by the conventional DSA. Finally an animal experiment had been performed using rabbits, and the branches of the thoracic and abdominal aorta had been demonstrated clearly by the contrast medium administrated from their earlobe vein. Then we considered that this system might be available enough for IV-DSA for human beings.

从1997年到2000年，我们对一种新设计的由冷却的CCD相机组成的DSA系统进行了研究。由于冷却后的CCD相机具有明显的高对比度分辨率，我们认为新系统应该能够胜任IV-DSA。首先搭建了DSA系统，该系统由X射线发生器、光学单元和数字处理单元组成。并对系统的成像能力进行了测试。根据使用人工血管的实际检查结果，我们判断新系统检测的图像的对比度分辨率优于常规DSA。最后用兔进行动物实验，经耳垂静脉注射造影剂后，可清晰显示胸、腹主动脉分支。然后我们认为这个系统可能足够用于人类的IV-DSA。
