Abstract: The method involves stimulating nuclear magnetization in investigation object, in the investigation region using at least one high frequency magnetic pulse. The MR signals received from an MR coil is used for at least one MR image. At least one micro coil tuned to the MR frequency and without connecting leads is inserted into the object under investigation, and the MR signals are processed so that the local change caused by the micro coil in the magnetic field arising from the HF pulse can be seen in the MR image. An Independent claim is also included for a magnetic resonance arrangement for implementing the method.

Abstract: The method involves acquiring in chronological order several MR data sets of the object under investigation. From each of the data sets a low resolution MR image (Ii) is reconstructed. By comparing these images an image transformation parameter (Tij) is derived. A high resolution MR image (I) is then reconstructed from the MR data sets based on the image transformation parameter. The position of image points can be determined in a low resolution image as a reference image and compared with the image points of the remaining low resolution images. From this comparison the image transformation parameter can be determined.
