Remote injection system for vascular intervention for treatment of CTO

The vascular intervention is performed with radioactive image guidance, so the operators are exposed to radiation. During the vascular intervention, the contrast media is injected often for providing clear images of target lesion. Repetitive injection task increases the procedure time and inconvenience. Also, accurate dosage is important to avoid the side effects from over usage of the contrast media. This work proposes a remote injection system that can remotely inject a contrast media by accurate dosage to reduce radiation exposure for treatment of CTO. The performance of the remote injection system was verified through experiments.
