METHOD AND SYSTEM FOR COMPENSATING STRAY MAGNETIC FIELDS IN A MAGNETIC RESONANCE IMAGING SYSTEM WITH MULTIPLE EXAMINATION AREAS

The invention describes a method for compensating stray magnetic fields (SF) in a magnetic resonance imaging system (1) with two or more examination areas (M1, M2, M3, M4, M5, M6), comprising the steps:- providing a value for a predefined first magnetic field (GZ1) to be applied in a first examination area (M1), in addition to a basic magnetic field (B0),- providing information defining a predefined sequence control pulse (GZ2) to be applied in a second examination area (M2),- determining a stray magnetic field (SF) in the second examination area (M2) for the case that the first magnetic field (GZ1) is applied in the first examination area (M1),- calculating a compensated sequence control pulse (CG) for the second examination area (M2) from the predefined sequence control pulse (GZ2) and the determined stray magnetic field (SF),- applying the compensated sequence control pulse (CG) to the second examination area (M2).The invention further describes a respective system, a control device and a magnetic resonance imaging system.
