Minimally invasive interventions benefit from image guidance during instrument positioning. To ensure high image quality, MR-guided interventions are preferably performed in closed bore systems using MR markers and passive tracking sequences to localize and monitor the interventional device. In this work we accelerate a passive marker tracking sequence designed for needle-guided procedures using a simultaneous multi-slice excitation. With this technique the acquisition time is reduced by 33%, which results in a higher temporal fidelity while maintaining targeting accuracy.
