摘要： In a method and apparatus for automatic magnetic resonance imaging of a patient, an MR overall image is composed from several MR partial images. An MR overview image is received by a process that determines several scanning ranges based on the MR overview image. The MR scanning ranges are characterized by a length along a first direction. For all MR scanning ranges: the length along the first direction is set equal to the length of the longest MR scanning range in the first direction.

摘要： A dielectric element is formed of a dielectric material exhibiting a magnetic resonance relaxation time, with a relaxation agent incorporated in the dielectric material that reduces the relaxation time of the dielectric material. The dielectric element is adapted for placement on a subject while magnetic resonance data are acquired from the subject, and locally influences the B1 field distribution in the subject during the acquisition of magnetic resonance data.

摘要： In a method and an apparatus for acquiring magnetic resonance data, a region of a subject is exposed to a spin echo magnetic resonance pulse sequence that includes a refocusing radio-frequency pulse flip angle evolution that causes magnetic resonance signals to be emitted from the region with a signal evolution following each excitation radio-frequency pulse. The signal evolution is sampled to extract two or more sets of sampled data therefrom respectively with different contrast weightings of tissues in the region. The multiple sets of sampled data are made available as respective outputs in a form allowing multiple different images of the region to be generated therefrom, respectively with said different contrast weightings. For example, a spin density-weighted image and a T2-weighted image, or a T2-weighted image and a heavily T2-weighted image, thus can be generated by sampling from the same variable-flip-angle echo train.

摘要： An embodiment of the invention relates to the generation of MR images of a volume section within an examination object by way of a magnetic resonance scanner. In at least one embodiment, the following steps are performed: generating at least one of the MR images; automatically performing a number of quality inspections on the at least one MR image; and, should one of these quality inspections fail, an action is automatically performed in order to improve a quality when generating more of the MR images.
