Systems and methods for landmark correction in magnetic resonance imaging

摘要

Systems and methods for landmark correction in Magnetic Resonance Imaging (MRI) are provided. One method includes acquiring at least one calibration image or at least one localizer image of an object, identifying in the calibration or localizer images a region of the object as a reference point, wherein the reference point defines a landmark position. The method further includes determining an offset between an initial landmark position and the identified landmark position. The method also includes using the determined offset for MRI.

主权项

1. A non-transitory computer readable storage medium for landmark correction in Magnetic Resonance Imaging (MRI) using a processor, the non-transitory computer readable storage medium including instructions to command the processor to:
acquire at least one calibration image or at least one localizer image of an object; identify in the calibration or localizer images a region of the object as a reference point, the reference point defining a landmark position; determine an offset between an initial landmark position and the identified landmark position; and use the determined offset for MRI; wherein the at least one localizer image comprises a plurality of two-plane image slices and the instructions command the processor to identify a torso outline of the object using an axial image of the plurality of two-plane images.
