A system was designed for real time shimming to compensate respiration induced field changes. The feasbility of real time shimming is demonstrated for brain imaging at 7T, showing a marked increase in phase stability and image quality compared to scans without this compensation. The system can be used with all types scans, as it does not require any sequence modification.
