Abstract：The digital subtraction angiography has been widely used in clinical medicine. First, the
principle of digital subtraction angiography was introduced in this paper. Then two cases of analysis and
maintenance of GE Innova 3100-IQ digital subtraction angiography in our hospital were described. The
failure of “X-RAY not available” was caused by the line damage between “RTAC Gitane” board to “C1
bulkhead J11”. The failure of “X-ray stop” when hand brake was pressed was caused by the damage of
the inverter. Finally, the causes, detection process and the solution of the two failure were introduced
respectively. We hope that this article can offer a reference for medical equipment maintenance personnel.
