1. A method for operating a magnetic resonance (MR) imaging apparatus, comprising an MR scanner configured to receive an examination subject therein, and a control computer configured to operate the MR scanner to acquire MR data from the examination subject therein, said MR scanner comprising a gradient coil system, said method comprising:
entering control parameters into said control computer that influence a timing sequence of gradient pulses emitted by said gradient coil system during the acquisition of said MR data; from said control computer, retrieving reference control parameters from a database that designate a degree of mechanical force flow that occurs in said gradient coil system when said MR scanner is operated to acquire MR data using the reference control parameters; in said control computer, comparing the control parameters to the reference control parameters with respect to a comparison criterion that designates an acceptable level of said mechanical force flow in said gradient coil system during the acquisition of said MR data; in said control computer, automatically determining, dependent on said comparing, whether said magnetic resonance data should be acquired by operating said MR scanner according to the control parameters that were entered into said control computer; and from said control computer, only if said determining produces a determination result that said MR data should be acquired by operating said MR scanner according to the control parameters that were entered into said control computer, then formulating or selecting an MR data acquisition sequence from said control parameters and proceeding to operate said MR scanner to acquire said MR data according to said MR data acquisition sequence. |
