Abstract: An MR apparatus creating a timeline suitable for data acquisition in several temporal phases. The MR apparatus including a method for creating a timeline TL2 having a scan time of TS1 based on a reference timeline TL0 having a scan time of TS. The method setting start points in time of scans SC1, SC3 and SC4 in the timeline TL2 to the same points in time as those in the reference timeline TL0, respectively. The method also setting the start point in time of the scan SC2 in the timeline TL2 to a sum of the scan time TS1 and a delay time TD1 with respect to the scan SC1 in the timeline TL2.

Abstract: A magnetic resonance apparatus configured to select a coil mode that includes a combination of coil elements to be used when a subject is scanned from within a plurality of coil elements and configured to execute a predetermined scan for acquiring data on the subject using the selected coil mode is provided. The magnetic resonance apparatus includes a coil device having n coil modes, a selecting unit configured to select, from within the n coil modes, a candidate for the selected coil mode, a scanning unit configured to execute a first scan for acquiring the data on the subject using the candidate, and a sensitivity map preparing unit configured to prepare a sensitivity map of the candidate based on data obtained by the first scan.
