摘要
该文主要针对JJG1067——2011《医用诊断数字减影血管造影DSA系统X射线辐射源》涉及到的辐射照射的量(空气比释动能率、吸收剂量等)的含义与X射线管的焦点进行更深一步的探讨。
This paper mainly aim at two parameters involved in the JJG1067-2011 verification regulation of X ray radiation source for medical diagnostic digital subtraction angiography DSA system. One is the meaning of radiation exposure( air kerma rate or absorbed dose). The another one is the further discussion for the focus of X ray tube.
