Raw data save

About this task

Raw data is unreconstructed data used to create the MR image or MR spectroscopy results. The service engineer may ask you to save raw data if an image reconstructs with an artifact or distortion. This information can help determine the cause of the artifact or problem. For certain applications such as spectroscopy, raw data is saved automatically to Pfiles, which are stored in the /usr/g/mrraw directory. In cases where the raw data is not automatically saved, it is possible to create a Pfile from the raw data acquired during the most recent scan. This is done via the Raw File Manager tool. It is also possible to set the research CV, autolock =1, to generate Pfiles for each scan. This functionality is supported by most applications.

Use these steps to save Raw data immediately after a scan has completed. Because the raw data resides in the temporary memory of the system, you must save the raw data before starting the next series. Please be patient during the raw data transfer.

    • The raw data is saved on the system hard disk until it is removed.
    • Raw data uses disk space, and, as the disk becomes full, system performance can be degraded.
  5. Click File > Exit.
