Keywords: Safety, Brain ConnectivityEfficient monitoring of the specific absorption rate (SAR) in parallel-transmission MRI is performed by evaluating the RF power deposition on specific SAR matrices called Virtual Observation Points (VOPs). But given the various sources of uncertainties that occur in practice (head placement, anatomy, precision of the body model to name a few), a challenging task remains to determine a suitable safety margin to be applied on the VOPs to offer a tradeoff between safety and scanning performance. In this work, as a first step towards this, we propose a workflow to tackle this problem for brain imaging at 11.7 Tesla.
