A method for controlling a magnetic field gradient applied in an MRI System during an imaging sequence, the method comprising: - determining a first gradient parameter (G N1) representing a first maximum value of the applicable magnetic field gradients applied over time in view of a heat generated by the applied magnetic field gradients, wherein the first gradient parameter (G N1) represents the first maximum value of the magnetic field gradients that is suitable for use in a first use scenario in which the imaging sequence is repeated over a first period of time - determining a second gradient parameter (G N2) representing a second maximum value of the applicable magnetic field gradients applied over time in view of a heat generated by the applied magnetic field gradients, the second maximum value being different from the first maximum value, the second gradient parameter (G N2) representing the second maximum value of the magnetic field gradients that is suitable for use in a second use scenario in which the imaging sequence is repeated over a second period of time longer than the first period of time, wherein the first maximum value is higher than the second maximum value, - determining a current operating parameter of the MRI system, - selecting one of the first gradient parameter and the second gradient parameter for the imaging sequence in dependence of the determined current operating parameter, wherein the method for controlling the magnetic field gradient is started with the first maximum value as a start value independent of the determined current operating parameter, and the method switches to the second maximum value when the determined current operating parameter indicates that a cooling capacity of the MRI system is exceeded when future imaging sequences use magnetic field gradients with maximum values as defined by the first maximum value, characterized in that the determining the current operating parameter comprises determining by a temperature sensor a temperature in a cooling module used to cool a gradient module configured to generate the magnetic field gradients in the MRI system. - determining a first gradient parameter (G N1) representing a first maximum value of the applicable magnetic field gradients applied over time in view of a heat generated by the applied magnetic field gradients, wherein the first gradient parameter (G N1) represents the first maximum value of the magnetic field gradients that is suitable for use in a first use scenario in which the imaging sequence is repeated over a first period of time - determining a second gradient parameter (G N2) representing a second maximum value of the applicable magnetic field gradients applied over time in view of a heat generated by the applied magnetic field gradients, the second maximum value being different from the first maximum value, the second gradient parameter (G N2) representing the second maximum value of the magnetic field gradients that is suitable for use in a second use scenario in which the imaging sequence is repeated over a second period of time longer than the first period of time, wherein the first maximum value is higher than the second maximum value, - determining a current operating parameter of the MRI system, - selecting one of the first gradient parameter and the second gradient parameter for the imaging sequence in dependence of the determined current operating parameter, wherein the method for controlling the magnetic field gradient is started with the first maximum value as a start value independent of the determined current operating parameter, and the method switches to the second maximum value when the determined current operating parameter indicates that a cooling capacity of the MRI system is exceeded when future imaging sequences use magnetic field gradients with maximum values as defined by the first maximum value, characterized in that the determining the current operating parameter comprises determining by a temperature sensor a temperature in a cooling module used to cool a gradient module configured to generate the magnetic field gradients in the MRI system.
