Claim 13:
14. The magnetic resonance tomograph according to claim 13, wherein the high-frequency controller is configured to generate, with the high-frequency-coils, at least one excitation pulse for recording the first navigator data and at least one excitation pulse for recording the second navigator data,
wherein the receiving coil is configured to record the first and the second navigator data, wherein the first navigator data comprises first signal amplitudes and the second navigator data comprises second signal amplitudes,
wherein the signal processing system is configured to receive the first navigator data and the second navigator data by the receiving coil,
wherein the signal processing system is configured to interpole the first signal amplitudes and the second signal amplitudes respectively to a regular grid on a spherical surface, and
wherein the signal processing system is configured to calculate the first coefficients based on the first signal amplitudes, wherein the first coefficients are first coefficients of spherical harmonics, and wherein the signal processing system is configured to calculate the second coefficients based on the second signal amplitudes, wherein the second coefficients are second coefficients of spherical harmonics.
