Abstract

A magnetic resonance imaging (MRI) system including a memory for storing machine executable instructions and a processor for controlling the magnetic resonance imaging system. The MRI system for performing a plurality of MRI scans for acquiring magnetic resonance data from a target volume of a patient in accordance with respective predefined scan geometries. The execution of the machine executable instructions causes the processor to control the MRI system to at least: perform a first calibration scan; perform a second calibration scan; generate geometry transformation data; determine a deviation of the target volume caused by a movement of the patient; update each of the predefined scan geometries and the second scan geometry as a function of the geometry transformation data; and perform at least one MRI scan of the plurality of MRI scans to acquire image data in accordance with the respective updated predefined scan geometry.
