US 12,078,702 B2 · Image signal representing a scene

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.

Dependent claims

A method of reconstructing an image of a subject in a MRI IT system comprising:

acquiring k-space data including oversampling k-space data for a prescribed field of view (FOV) image of the subject;
and storing the acquired data and the specific angulation data used for the acquisition in a non-transitory storage medium;
and processing the stored data to reconstruct a first extended field view (EFOV) image;
cropping the first EFOV image to generate the prescribed FOV image without aliasing or wrap artifacts;
and displaying the prescribed (FOV) image;
and reusing the stored data to re-reconstruct a second extended (EFOV) image;
and displaying the second extended field of view (EFOV) image.
