A method of correcting resultant magnetic fields in a magnetic resonance examination system based on a field probe system, wherein the field probe system comprises several field probes and is configured to measure a magnetic field distribution of a main magnetic field and/or a gradient magnetic field in an examination zone of the magnetic resonance examination system due to a switching operation of a gradient system of the magnetic resonance examination system and/or due to a magnetic field disturbance originating externally, the method comprising the steps of - by a control module configured to control the field probe system, activating the field probe system to measure the magnetic field distribution in an earlier configuration simultaneously with an acquisition of magnetic resonance imaging signals from the examination zone in the earlier configuration; - by the control module, determining a response relation representing the measured magnetic field distribution in the earlier configuration due to said switching operation of the gradient system and/or due to said magnetic field disturbance originating externally, and storing the response relation in a memory; - acquiring magnetic resonance imaging signals from the examination zone in a current configuration; - performing a compensating activation of gradient coils of the gradient system in the current configuration based on the response relation representing the measured magnetic field distribution in the earlier configuration; and/or - applying corrections in reconstruction of a magnetic resonance image from the magnetic resonance imaging signals acquired in the current configuration based on the response relation representing the measured magnetic field distribution in the earlier configuration; wherein in the earlier configuration, the field probes and a body part of a subject are positioned in the examination zone, and in the current configuration, a different body part of the same subject or a body part of another subject is positioned in the examination zone. - by a control module configured to control the field probe system, activating the field probe system to measure the magnetic field distribution in an earlier configuration simultaneously with an acquisition of magnetic resonance imaging signals from the examination zone in the earlier configuration; - by the control module, determining a response relation representing the measured magnetic field distribution in the earlier configuration due to said switching operation of the gradient system and/or due to said magnetic field disturbance originating externally, and storing the response relation in a memory; - acquiring magnetic resonance imaging signals from the examination zone in a current configuration; - performing a compensating activation of gradient coils of the gradient system in the current configuration based on the response relation representing the measured magnetic field distribution in the earlier configuration; and/or - applying corrections in reconstruction of a magnetic resonance image from the magnetic resonance imaging signals acquired in the current configuration based on the response relation representing the measured magnetic field distribution in the earlier configuration; wherein in the earlier configuration, the field probes and a body part of a subject are positioned in the examination zone, and in the current configuration, a different body part of the same subject or a body part of another subject is positioned in the examination zone. - applying corrections in reconstruction of a magnetic resonance image from the magnetic resonance imaging signals acquired in the current configuration based on the response relation representing the measured magnetic field distribution in the earlier configuration; wherein in the earlier configuration, the field probes and a body part of a subject are positioned in the examination zone, and in the current configuration, a different body part of the same subject or a body part of another subject is positioned in the examination zone. in the earlier configuration, the field probes and a body part of a subject are positioned in the examination zone, and in the current configuration, a different body part of the same subject or a body part of another subject is positioned in the examination zone.
