Multi Station: scan the series

About this task

Use these steps to scan a Multi Station series to acquire a peripheral run-off exam. To reduce the table movement, acquire the localizer scans from bottom to top and acquire the run-off series from top to bottom.

Step-by-step instructions

  1. Skip to step 7 if you are not performing a mask series.
  2. When you are ready to initiate prescan for the Multi Station mask (or arterial) series, select the last station of the meta-series.
  3. Click Save Rx.
  4. Acquire Prescan for all locations.
    • If the Calibration in Prescan parameter (located on the Details screen) is set to On, a calibration scan is automatically acquired if ASSET, PURE or SCENIC are selected. Click Prescan All.
    • Depending on the patient orientation (head or feet first) the meta-series will be prescanned in reverse order: the last series is pre-scanned first and the first series last.
    • When prescan has completed, the table is at the location needed for station one and no table movement is needed when the sequence is ready to begin.
    • When a station is in the PSCD state, scan parameters cannot be edited.
  5. Select series one of the desired meta-series and continue with the scan process as needed.
  6. Click Scan Mask to scan all series within the Mask meta-series.
    • All stations within the Mask meta-series are scanned from top to bottom.
    • The system stops after all the Mask meta-series are acquired. This allows you to prepare for the contrast injection.
  7. Prepare the patient for contrast injection.
  8. Select the first station of the arterial meta-series.
  9. Click Scan A/V.
    • If you are using Fluoro Trigger, the system switches to that mode. Make adjustments to the Fluoro Trigger image and then click Go 3D when the bolus fills the vessel and provide breathing instructions to the patient.
    • If you are using SmartPrep, the system initiates it. The system prompts you in the message window when to begin giving contrast. Once contrast is detected, instruct the patient to hold his or her breath.
    • Once the first station is done scanning, the patient can resume breathing.
    • The system scans the top, middle, and bottom arterial stations, moving the table automatically between stations.
    • If a series is cut from the Workflow Manager during a Multi Station scan, the table may not stop and pause for initiation of the next phase of the scan.
    • Until all stations are tagged as SCND, you will not be allowed to save a second meta-series in an exam.
    Note: If a venous meta-series is prescribed, the table begins scanning the venous meta-series from bottom to top after the arterial meta-series is completed.

    The meta-series can be saved as a protocol.
