 Abstract: Recently, the potential impact of a limited MR-based field-of-view (FoV) in whole-body MR/PET attenuation correction has been shown. In MR/PET the tissue attenuation map can be calculated from the MR images. However, the FoV restriction may cause a truncation of the MR data for bigger patients and therefore can bias the PET data reconstruction. In this work, we will show exemplarily for 2DFT spin-echo sequences a method that offers an extended FoV in the transversal plane of up to 600mm using a gradient field that compensates B0 inhomogeneities.
