Preparations in the Coronal and Sagittal slices
In the second preparation page, you can crop the views to include all relevant treatment areas in the Outer Contour and (if a couch top was selected) adjust the couch top in the coronal and sagittal slices.
Select Crop ①. Drag the sides of the blue rectangles to include the area of patient data that the algorithm takes into account when creating the Outer Contour.
Cropping outside the range of the planning CT in the superior or inferior direction causes parts of the couch top that are outside of this range to be ignored during dose calculation.
Select Adjust ②. Drag the blue couch top representations (if available) to position the couch top within the scan images.
Use the fixation hole markers represented in the blue couch top representations for guidance.
Select Next ③ to proceed.
