摘要： A device is disclosed for superposed MRI and PET imaging and includes an MRI tube that has a first field of view along its longitudinal direction, and a multiplicity of PET detection units arranged opposite one another in pairs about the longitudinal direction. In at least one embodiment the many PET detection units define a second field of view along the longitudinal direction, and their arrangement density along the longitudinal direction is optimized such that the second field of view substantially corresponds to the first field of view.

摘要： A method is disclosed for performing a combined magnetic resonance/positron emission tomography scan of an examination object in an MR/PET system. An embodiment of the method entails acquiring first magnetic resonance data using a first readout gradient field. The first readout gradient field is chosen such that, at a location of the field of view of the magnetic resonance system, a distortion caused by a nonlinearity of the first readout gradient field and a distortion caused by a B0 field inhomogeneity substantially cancel each other out. First magnetic resonance images for planning the combined magnetic resonance/positron emission tomography session and determining an attenuation correction map for a positron emission tomography scan are determined on the basis of the first magnetic resonance data. Positron emission data and second magnetic resonance data are acquired using a second readout gradient field.

摘要： According to an embodiment of a method, a first readout gradient field is determined in such a way that a distortion caused by a non-linearity of the first readout gradient field and a distortion caused by a B0 field inhomogeneity are essentially cancelled at a first location of a field of view of the magnetic resonance facility. Moreover, a second readout gradient field is determined in such a way that a distortion caused by a non-linearity of the second readout gradient field and a distortion caused by a B0 field inhomogeneity are essentially cancelled at a different second location of the field of view. Finally, a multiecho sequence is performed, wherein first magnetic resonance data is captured using the first readout gradient field after a 180° pulse and second magnetic resonance data is captured using the second readout gradient field after a further 180° pulse.
