Abstract :
In order to improve amenity for patients in hospitals, we have designed an open type of magnetically shielded room (MSR) for magnetic resonance imaging combined with cancelling coils, which enable transparent opening. First, an optimal arrangement of cancelling coils is investigated using three-dimensional magnetic field analysis. Secondly, the validity of the analysis method is verified and the realization of an open type of MSR designed both for keeping low leakage flux density and for maximizing the opening is confirmed by experiments using a small MSR model
