AIR xTM brain

Use these steps to acquire an AIR xTM brain scan.

About this task

Consider the following before acquiring an AIR xTM brain scan:
  • AIR xTM calculations may be compromised for patients with an artificial eye.
  • The patient position must be supine.

Step-by-step instructions

  1. From the Protocol screen, select a head category, and then select a head protocol.
  2. Acquire a whole brain, 2D 3-plane FGRE, or SSFSE localizer. SSFSE localizer is preferred to ensure the best results. The 3-plane localizer must meet the following criteria:
    • Frequency and phase resolution >= 192
    • Slice thickness <= 15 mm
    • Slice coverage for all axial, sagittal, coronal planes >= 10 cm. When the HNU comfort tilt is used, or the patient’s head is rotated to the left or right, please use slice coverage >= 16 cm to ensure best results.
    • Slice gap <= 5 mm
    • TE for SSFSE <= 80 ms
  3. From the Workflow Manager, select Task 2 and click Setup to review the scan parameters.
  4. To view the Details screen, click the arrow in the upper right corner of the scan parameter screen.
  5. From the Anatomical Reference menu on the Details tab, select an option:
    • None
    • ACPC
      • Temporal Lobe
    • IAC
    • OML
    • Orbits
    • Optic Nerves
      • Pituitary
      • Circle of Willis

  6. From the Anatomical Plane menu on the Details tab, select an option. Note that the scan plane options are based on the selected Anatomical Reference.
    • Axial
    • Sagittal
    • Sagittal Left (only appears if Optic Nerves is selected from Anatomical Reference menu)
    • Sagittal Right (only appears if Optic Nerves is selected from Anatomical Reference menu)
    • Coronal

    Result

    The AIR xTM computed results display in the Graphic Rx viewports as soon as the computation completes after the localizer scan.

  7. Make graphic prescription adjustments and any other scan parameter changes as needed.
  8. Link all subsequent tasks that require the same Anatomical Reference selections as task 2.
  9. Click Save Rx.

    Result

    The prescription gets propagated to the linked destination tasks, which get auto-saved if it was specified in the link creation.

  10. From the Workflow Manager, select another task that has a different reference line.
  11. Click Setup.
  12. From the Details tab, select the Anatomical Reference option.

    Result

    The system displays the new AIR xTM-computed results in the Graphic Rx viewports.
  13. Link all subsequent tasks that require the same Anatomical Reference selections as the new task.
  14. Click Save Rx.
