Abstract
In order to ensure the safety and effectiveness of digital subtraction angiography (DSA) system, it is essential to conducted performance testing and control quality of DAS system regularly. According to the national metrology veriifcation regulation (JJG 1067-2011) of X-ray radiation source of medical diagnostic digital subtraction angiography (DSA) system, this paper introduced the testing methods of air kerma rate, HVL, X-ray tube voltage, minimal size of simulate vascular, spatial resolution, low contrast resolution, contrast linearity and subtraction angiography performance impact.关键词
