Customized spatial saturation pulse sequence for suppression of artifacts in MR images

摘要

Artifacts in MR images caused by signals emanating from outside the design spherical volume (DSV) of the system are suppressed using customized spatial saturation pulse sequences interleaved with imaging pulse sequences. The spatial saturation pulse sequences are each customized to a specific region and are stored in a library for selective use when needed to suppress artifact producing signals emanating from specific regions outside the DSV.
