Abstract
A method for correcting a B0 inhomogeneity in a magnetic resonance scan with a magnetic resonance tomograph is provided. The magnetic resonance tomograph includes a controller, a radio frequency unit, and a transmitting antenna. In the method, the controller determines a transmission signal that is suitable for correcting an effect of an inhomogeneity of a static B0 magnetic field in an examination volume by the Bloch-Siegert effect. The transmission signal is emitted into the examination volume.

A method for correcting a B0 inhomogeneity in a magnetic resonance scan with a magnetic resonance tomograph, wherein the magnetic resonance tomograph comprises a controller, a radio frequency unit, and a transmitting antenna, wherein the method comprises:
- determining, by the controller, a transmission signal for correcting an effect of a magnetic field inhomogeneity in an examination volume by the Bloch-Siegert effect;
- and
- emitting the transmission signal into the examination volume.
A magnetic resonance tomograph comprising:
- a controller configured to determine a transmission signal for correcting an effect of a magnetic field inhomogeneity in an examination volume by the Bloch-Siegert effect;
- a radio frequency unit;
- and
- a transmitting antenna configured to emit the transmission signal into the examination volume.
In a non-transitory computer-readable storage medium that stores instructions executable by a controller of a magnetic resonance tomograph to correct a B0 inhomogeneity in a magnetic resonance scan with the magnetic resonance tomograph, wherein the magnetic resonance tomograph further comprises a radio frequency unit and a transmitting antenna, wherein the instructions comprise:
- determining, by the controller, a transmission signal for correcting an effect of a magnetic field inhomogeneity in an examination volume by the Bloch-Siegert effect;
- and
- emitting the transmission signal into the examination volume.
