  - Doing DQA calibration
    The DQA tool determines proper gradient polarity and proper gradient wiring by scanning a series of axial and coronal images of the DQA III phantom.
  - Troubleshooting the Daily Quality Assurance (DQA) II tool
    If problems are encountered while using the Daily Quality Assurance (DQA) calibration procedure, refer to the following guidelines for troubleshooting.
  - Doing the Echo Planar Test
  - Deionization procedure
  - HIS/RIS Setup and Troubleshooting
  - ICN On/Off procedure for Sun 4100, 4170, and Dell R620
  - Running LVShim - Gradshim
  - Saving information
    Save the current configurations and files in order to restore them later, if needed.
  - Doing a check scan
    A check scan is done at the conclusion of many procedures. This functional check assures the unit is in good clinical working order.

Deionization procedure

See the latest revision of the GEHC Deionization Kit - DVMR Manual (DOC1805763) available from the online documentation library.

After deionization and filtering, top up the Gradient Coolant (GC) and Power Electronics (PE) coolant. See Filling the coolant.
