Abstract
Described herein are various embodiments of techniques for controlling creation of a magnetic resonance (MR) image from a magnetic resonance imaging (MRI) scan of a subject using an MRI scanner, through real-time, dynamic control of the MRI scanner during the MRI scan and/or of processing during the MRI scan of acquired MR signals as part of generating MR data for creation of the MR image. More particularly, some embodiments described herein relate to identifying changes that occur in a magnetic field within an MRI scanner during a course of an MRI scan. In response to changes in the magnetic field, an MRI scanner may be adjusted to change a way in which additional MR data is captured and/or a processing of captured MR signals (that are to be used in generating an MR image) may be adjusted.
