In a magnetic resonance apparatus and an operating method therefore, a data acquisition sequence for operating the apparatus is repeatedly reviewed in a number of ascertainment passes executed in a processor, each ascertainment pass involving a calculation step, and in each calculation step a determination is made as to other respective values of data elements used in a previous calculation step have changed. If no change has occurred, a re-calculation in the current calculation step is not implemented, thereby reducing the time and computing capacity that are needed to generate a final data acquisition sequence.

Magnetic resonance apparatus and operating method therefor

In a method for operating a medical imaging examination apparatus having multiple subsystems controlled by a control computer in a scan sequence, a control protocol for the scan is provided to the control computer, which determines sequence control data for the control protocol that define different functional subsequences of the scan, with different effective volumes assigned to each functional subsequence. Current ambient conditions of the apparatus are determined that are decisive for the determined relevant sequence control data and associated effective volumes. Control signals for the scan are determined from the sequence control data, the effective volumes and the current ambient conditions determined that optimize the functional subsequences of the scan.
