Basic Interactive Interface Workflow
CHAPTER 10: SEQUENCER
SEQUENCER constantly communicates with the linac over an Ethernet or a serial
connection. Actual geometric values from the linac show in the Verified Treatment window.
The steps below begin at the point when you mode up the linac. The preceding steps are the
same as the Basic SEQUENCER Workflow above.
1. Mode up the linac.
SEQUENCER compares the prescribed parameter values against the machine parameter
values. SEQUENCER prevents treatment if one or more parameters are out of tolerance.
2. Treat the first field and make during and or post-treatment portal images if necessary.
3. Click Record in the Record Treatment dialog box or Record Port dialog box (or
Composite Record Treatment dialog box).
4. Select the next treatment field, then mode up the linac.
5. Change the patient position if necessary.
6. Treat the next field and make portal images if necessary.
7. Continue to treat the remaining fields or end the session if necessary.
8. Capture charges.
Using Auto-Setup without Console Setup
If you use a linac other than an Elekta Precise, a Varian EXCI or a Varian 4DITC, you can
Auto-Setup the parameter values. The difference is that you cannot manually change values
from MOSAIQ in the same way as Console Setup, which is in the subsequent section.
1. In the Treatment Delivery Table dialog box, double-click the field to treat.
2. In the Verified Treatment window, click Auto Setup.
3. In the Auto-Setup Parameters message box, click Yes.
4. Go into the treatment room to make sure the Auto-Setup parameters are correct.
On Varian non-EXCI linacs, you have two minutes from the time you
click Yes until you hold the enable bars and press the Auto button on
the pendant. If you take longer than two minutes, you must re-do the
Auto-Setup.
Also, the gantry and collimator move only as long as you hold the
enable bars. You must continue to hold the enable bars until the
gantry and collimator are at the desired angles.
5. Use the Auto Motion feature for your linac as directed by your linac manufacturer.
