SEQUENCER Workflows<br />
SEQUENCER connects to your linac interactively or statically, depending on the interface.<br />
An interactive interface lets SEQUENCER communicate directly with the linac in real time.<br />
SEQUENCER must wait for data transfers when the interface is static. An example of an<br />
interactive interface is the interface to an Elekta Synergy linac. An example of a static<br />
interface is the interface to a Siemens Coherence linac. SEQUENCER sends the treatment<br />
field to the linac and verifies that the linac is correctly moded up before you can beam-on.<br />
The Varian 4DITC and Siemens Syngo is a special case because the interface only lets<br />
SEQUENCER record geometric machine and treatment data.<br />
Basic SEQUENCER Workflow<br />
The steps below apply to any SEQUENCER interface configuration after you select the<br />
patient and open the patient chart. Refer to Select a Patient for Treatment on page 261 in<br />
this section.<br />
1. Select the Treatment Calendar session that you want.<br />
SEQUENCER sends the treatment field data to the linac and opens the Verified<br />
Treatment window. You can use the Auto Setup option to setup the linac to deliver the<br />
selected treatment field.<br />
2. Select the first field to treat, then click Select<br />
If the Treatment Readiness Check dialog box opens, you must respond before you can<br />
continue.<br />
3. Setup the patient on the couch.<br />
If your department uses accessory barcodes, you must scan the accessory barcodes now<br />
to avoid an interlock.<br />
4. Make pre-treatment portal images if necessary.<br />
5. Mode up the linac.<br />
SEQUENCER compares the prescribed parameter values against the machine parameter<br />
values. SEQUENCER prevents treatment if one or more parameters is out of tolerance.<br />
6. Beam-on the linac.<br />
***Treating*** appears below the header. The Record Treatment dialog box opens<br />
when the treatment is complete.<br />
7. Treat the first field and make during and or post-treatment portal images if necessary.<br />
8. Type any relevant comments in the Note field of the Record Treatment dialog box.<br />
9. Click Record.<br />
The Verified Treatment window opens for the next field because you<br />
set the treatment order earlier. If you had not set the treatment<br />
sequence, the Treatment Delivery Table window will open after you<br />
record the treatment.<br />
