the impact of the central gap size is studied in this work in terms of the eddy current effects in a split whole-body MRI system which is designed for the PET-MRI multi-imaging technology. An optimal central gap size is found by analyzing the gradient performance and the eddy current effects as a function of the central gap size. The split MRI system with this central gap size could generate the smallest eddy current effects with good gradient performance. The findings in this work may provide indicators of potentially useful system configuration for the PET-MRI systems.
