摘要： A method is disclosed for determining a location of a subarea of an area under examination in a magnetic resonance system. The subarea is arranged at the edge of a field-of-view of the magnetic resonance system. In at least one embodiment of the method, at least one slice position is determined for an MR image in which the B0 field at the edge of the MR image satisfies a homogeneity value. For the slice position determined an MR image is acquired which contains the subarea at the edge of the field-of-view and the location of the subarea of the object under examination is determined through the location of the subarea in the MR image.

摘要： A method is disclosed for calculating a spatially resolved value of an absorption parameter for a positron emission tomography (PET) scan of an examination object via magnetic resonance tomography (MRT). Magnetic resonance data is acquired within a first region lying within a field of view of a magnetic resonance system and within a second region bordering on the first and lying at the edge of the field of view. The method includes the spatially resolved calculation of a first value of the absorption parameter from the first MR data within the first region and of a second value from the second MR data within the second region. A three-dimensional parameter map is obtained from the first value. This parameter map is extended by the second value such that within the first region and the second region the parameter map has the value of the absorption parameter in spatially resolved form.

摘要： A method is disclosed for acquiring magnetic resonance (MR) data for a plurality of layers of an object to be examined in a section of a magnetic resonance system having a basic magnetic field, wherein the section is located at the edge of a Field of View of the magnetic resonance system in the first direction. The method includes producing a first gradient field having a non-linearity of its location dependence in such a way that in the section the non-linearity compensates a local inhomogeneity of the basic magnetic field, and then multiple positioning of the object to be examined in a first direction, so the plurality of layers of the object to be examined perpendicular to the first direction successively includes the section. Finally, it includes the acquisition of magnetic resonance data for each of the layers with recording sequences.
