Radiation dose reduction in minimally-invasive intravascular procedures using a magnetic guidance system

In minimally-invasive intravascular procedures guide wires and catheters are used to diagnose and treat various vascular diseases. Rather high ionising radiation doses are employed to monitor these instruments during an intervention, creating an important health risk to the medical staff. To analyse the radiation usage, different interventions were recorded and the final results are presented. Further, to minimise the total radiation dose during navigation, an electromagnetic guidance system, which is currently under development, is presented.
