    摘要: In a magnetic resonance imaging system having a scanner having a magnetic field system, a radio frequency system and a control device, and a method for operating such a system, the control device generates a control signal sequence on the basis of a control protocol for the purpose of executing a number of scan procedures and a number of adjustments for adjusting the magnetic field system and/or the radio frequency system, at least the scan procedures are predetermined by the control protocol. The control protocol furthermore contains a number of local scan transition indicators assigned to the scan procedures, and on the basis of the scan transition indicators, in each case the control device checks to determine if, directly prior to a scan procedure, an adjustment may be applied. The control signal sequence is then automatically generated by the control device such that, if for a scan procedure the necessary adjustment may not be applied prior to that scan procedure, then the relevant adjustment will be executed in advance and/or adjustment parameter values from previously executed existing adjustments will be used.

    摘要: A magnetic resonance apparatus is operated with continuous movement of an examination subject through a measurement volume of the apparatus. At each successively-occupied position of the examination subject within the measurement volume during the continuous movement, magnetic resonance data are acquired with system parameters, each having system parameter values. Contemporaneously with each data acquisition at each position, the acquired data are evaluated as to the effect produced by the system parameter values employed to acquire the data. The system parameter values are then adapted to cause the effect to correspond to a target value, and the adapted system parameters are then used to acquire data at the next-successive position occupied by the examination subject in the continuous movement.
