1. A method for acquiring magnetic resonance (MR) data, comprising:
in a control computer configured to operate an MR scanner according to an MR data acquisition sequence in which mechanical flux of force will be produced in the MR scanner by a gradient system of the MR scanner that is operated according to said MR data acquisition sequence, receiving a signal representing a user input to the control computer of a user-selected factor that is involved in acquisition of said MR data by said MR scanner; in said control computer, automatically selecting a threshold value dependent on said signal, said threshold value designating an amplitude of said mechanical flux of force in a frequency band; from said control computer, operating said MR scanner according to said MR data acquisition sequence to acquire MR data from an examination object in said MR scanner, including application of a temporal sequence of gradient pulses along at least one gradient axis; during operation of said MR scanner according to said MR data acquisition sequence, monitoring a system variable of said MR scanner that is indicative of said mechanical flux of force in said frequency band; in said control computer, comparing the detected system variable with said threshold value to obtain a comparison result; from said control computer, automatically aborting, dependent on said comparison result, operation of the MR scanner in the MR data acquisition sequence; and if said operation of said MR scanner is not aborted, making the MR data acquired from the examination object with said MR data acquisition sequence available in electronic form as a data file at an output of said control computer. |
