2. Click the Offset was applied during treatment check box in the Offset group. This
indicates that you applied the shift before treating the patient.
3. Click the check box adjacent to the direction of the shift you want to apply, then click
the direction.
4. Type the shifts in the Known Components group. If you type a negative value the shift
direction will change. If you want to record known zero values, click the check box to
distinguish the zero value from an unknown, or blank value.
5. Type the date and time, then click the source in the Offset group.
If you specify a source, that source appears in the Description column of the Localization
Trend Review dialog box. This is useful if your department uses more then one type of
patient positioning device. If your third party source is not on the list, you or an
ELEKTA/Impac administrator can select the menu item to add the source.
6. If you have a six degree couch, type the coronal, sagittal, and transverse angle
information in the Known Components group.
On a Varian 4DITC, right-click in the Treatment Session In Progress
window after you send the plan to open the Third Party Offset
dialog box.
The shifts you specified in the Image Review window or Third Party Offset dialog box are
now part of the patient’s treatment record. You can use them immediately to calculate new
couch targets and later to find systematic setup variation, or Localization Offsets.
Distributed Registration Review
When you review images, you can assign a recorded third party offset to the images.
MOSAIQ then shows the images registered with the chosen offset. The Third Party Offset
Selection dialog box opens after you select the images to be registered. Refer to Figure 58.
