Abstract

In a method for operating a medical imaging apparatus having multiple subsystems, a control protocol assigned to a scan sequence to be performed is provided to a control computer that determines sequence control data for the control protocol, which define different functional subsequences of the scan sequence. Different effective volumes are assigned to each functional subsequence, and current ambient conditions of the apparatus are determined for the sequence control data and associated effective volumes. Control signals for the scan sequence are determined from the sequence control data, the effective volumes and the current ambient conditions that optimize the functional subsequences of the scan sequence locally, at least with regard to a sub-region of the respective effective volumes. During the scan, at least one change of a sub-region of a respective effective volume is determined and the control signals used for the ongoing scan are modified, dependent on the change, to maintain the aforementioned optimization.
