Abstract

To reduce instances of patient call back examinations and longer acquisition times in MRI, caused by features noticed at the periphery of a prescribed field of view (FOV) image, an extended field of view (EFOV) image is generated by storing k-space data including oversampling data, in a Picture Archiving and Communication System (PACS) and/or technician workstation. The saved k-space data is repurposed to re-reconstruct the (EFOV) image before any cropping operation on the prescribed FOV. In another application, the extended (EFOV) image is generated by repurposing stored k-space oversampling data, from adjacent or overlapping fields of view (FOV). The disclosed device and method can be used advantageously in a multi-station MRI IT system and/or spinal MRI examinations.
