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.

Abstract: Described herein are techniques to determine whether an image that would result from a magnetic resonance imaging (MRI) scan would satisfy quality metrics, such as by being of sufficient quality to permit a diagnostic read of the image. The determination may be based on signals emitted and captured by an MRI system during the MRI scan, permitting an automated determination of quality of an image that would result from an MRI scan. Some such techniques may be performed during the MRI scan, before the completion of the MRI scan, or after the MRI scan before or after magnetic resonance data (MR data) resulting from the MRI scan has been processed to generate an image from the MR data.
