The Scan Timeline for SmartPrep is shown above the viewport and includes a minimum
of three sections and some number of delays:
•
Delay - Represented as a circle with the time of the delay shown underneath.
•
SP Baseline - First rectangular section under the SP label and represents the base‐
line scan.
•
SP Monitor - Second rectangular section and represents the monitor scan. The
timeline represents a single monitor scan. As scans are taken, the timeline will fill
and then clear for the next monitor scan.
You can edit the Baseline and Monitor collection values by clicking [Revisit Set‐
tings].
• Diagnostic Scan - Third rectangular section and represents the diagnostic scan for
the SmartPrep series. When this is a multi-group series, a rectangular section is
shown for each group.
The last scout image taken at the current landmark is shown with a cut line that will allow
the monitor location to be specified. Moving the cut line will correspondingly change the
Monitor Location in the Baseline & Monitor Collection .
The collections for the SmartPrep parameters are located just below the Scan Timeline.
SmartPrep has two collections:
•
Contrast Collection - Allows contrast data to be specified for the study. In this area
you can: enable or disable the integrated injector, set manual IV contrast (if Inte‐
grated Injector is disabled), and set oral contrast values.
The contrast agent and its concentration are associated with the exam. All non-
scout series in an exam that has contrast will have the same values for agent and
concentration if contrast is enabled.
The volume of the contrast injected is associated with a series. Once contrast is in‐
jected in a series in an exam, all subsequent series are considered contrast series.
Refer to Enter Contrast Description section in the Scan chapter for more informa‐
tion .
• Baseline and Monitor Collection - Allows setup of the parameters controlling the
Baseline and Monitor scans. See the Set up a Scan section in this chapter for more
information.
The prescription for the baseline scan and for the monitor scans must be the same.
The [Revisit Settings] button, available from any of the SmartPrep steps, is active when
the scan is paused or aborted or when 40 scans have been taken in the monitor phase.
You can edit the Baseline and Monitor collection values by clicking [Revisit Settings].
When you select Revisit Settings:
• The diagnostic scan task is unconfirmed.
• If no baseline scan had been taken, the SmartPrep task is un-confirmed.
• If a baseline scan had been taken, the SmartPrep task is marked as skipped.
NOTE: Once the SmartPrep task is skipped you can no longer change SmartPrep
parameters. To enable SmartPrep again for the series, delete the unscan‐
ned diagnostic scan and represcribe the scan.
• The diagnostic task is selected and the settings displayed.
Skip the monitor phase and go directly into the diagnostic scan. If you click [Skip to Diag‐
nostic] to transition to the diagnostic scan, the SmartPrep task is set to skipped.
Continue to the step of taking the Baseline Scan.
