Abstract
A phase difference caused by eddy currents is determined for an MR system. First MR data is acquired with a first sequence by irradiating at least one RF pulse having an RF excitation pulse, importing a first test gradient during or after the RF excitation pulse, applying a read-out gradient, and acquiring the first MR data while the read-out gradient is switched, so the first MR data is acquired for at least one K-space line. Second MR data is acquired with a second sequence by importing a second test gradient during or after the RF excitation pulse, and applying the read-out gradient. The second MR data is acquired while the read-out gradient is switched, so the second MR data is acquired for the at least one K-space line. The phase difference per voxel is determined using the first MR data and the second MR data.
