1. A method of magnetic resonance (=MR) imaging with spatial encoding for generating an image of an object of investigation inside an MR apparatus, the method comprising the steps of: a) selecting a volume of interest within the object of investigation; b) applying a radio frequency (=RF) pulse to generate a transverse magnetization within the object of investigation; c) effecting spatial encoding through application of spatially encoding magnetic fields; d) recording and storing MR signals originating from the object of investigation and assigning those signals to old MR data; e) physically removing the object of investigation from the MR apparatus following step d); f) repositioning the object inside the MR apparatus following step e); g) repeating steps a) through d) for recording further MR signals originating from the same object of investigation to record and store new MR data, whereby step c) is performed by undersampling the k-space for shortening a measurement time; h) correcting the old MR data recorded in step d) for changes in a new position of the object of investigation relative to the MR apparatus in step g); i) correcting the old MR data recorded in step d) for changes in a sensitivity and exact spatial positioning of the RF receiver coils of the MR apparatus in step g); j) correcting old MR data recorded in step d) for changes in an actual magnetic field shimming of the MR apparatus in step g); and k) reconstructing a high resolution MR image of the object of investigation from a synthesis of the old MR data recorded and stored in step d) and the new MR data recorded in step g).
