3. In the Treatment Field Definition dialog box, configure the field definition for the new
field.
The new field you made appears in the Diagnoses and Interventions window above the
diagnosis. Because you made it from the Treatment Delivery Table dialog box, it was not
assigned to a radiation prescription site. You must drag and drop this field to the desired
Rx for dose and fractions to be tracked. Make sure you click the Dosimetry button.
4. Click OK.
Changing a Treatment Field
Before you treat a patient, you can change one or more of the treatment fields without
closing the Treatment Delivery Table dialog box.

right-click or press F4 to open the menu.

also add portal images at this time. If you change the linac, SEQUENCER tells you that
the machine characterization is different.
4. Click OK and the Field Delta View dialog box opens.
The Field Delta View shows all changes highlighted in yellow. The Field Delta View
helps you make sure that you do not save a change that you did not intend to make. You
can configure the Field Delta View to appear or not appear from the Field Edit Rules
group in the Clinical (RO) tab of the Department Setup.
5. Click Accept to save your changes.
If you click Return, the changes are not saved, the Field Delta View dialog box closes
and the Treatment Field Definition dialog box opens again.
6. Approve the treatment field definition if that is necessary for your department.
CBCT Instructions
Refer to CBCT Acquisition in Chapter 6 on page 218 for more information on CBCT
acquisition. This section applies to Elekta machines with Synergistiq.
1. Make a new treatment field, in which the field type is CT or MVCT for Siemens Syngo
machines. You can copy a current field and change the Type field value (not a required
change for Varian or Siemens). All fields must have identical table values.
If have an Elekta XVI, you must select a preset. XVI will prompt you
for a preset at the time of acquisition.
2. When a patient has multiple prescription sites with different CTs/Structure Sets, on the
Treatment Delivery Table, select a field from site 1.
