Abstract
An MRI system produces magnetic field gradients along physical axes during a patient scan. The gradients are specified as logical gradient waveforms in a pulse sequence and these are stored in a logical vector table. A physical vector table is produced by rotating amplitude values in the logical vector table, and the resulting rotated amplitude values are used to calculate the heating in each gradient axis of the MRI system.
