Note: Positioning accuracy is only validated for points within the treatment volume.
Note: For a long table-top offering uniformity

, WET (Water Equivalent Thickness)
uniformity is only guaranteed for a position within the ranges of the treatment
volume. This is relevant only for those positions where the beam passes through the
table in the RT Ion plan beams geometry definition.
The PPS is capable to move and place a zone of interest outside the treatment
volume. However, positioning the PPS outside the treatment volume requires you to
exercise specific care for patient positioning verification.
The accuracy in the treatment volume is valid for left and right elbow configurations.
Note: The Patient Positioning System (PPS) is capable of positioning a point of the
treatment volume at isocenter within the required accuracy and repeatability values.
These values are valid for both small correction movements and large absolute PPS
movements.
Whenever you confirm a position outside the treatment volume, the following
message appears on the hand-pendant:
Position outside treatment volume. Position verifications are
mandatory.
Press OK to validate your selection.
Using the Couch
Note: The following information is valid for the kVue, kVueOne and CIVCO couch.
Figure 7-3 shows a detailed view of the treatment volume displayed by Figure 7-2.
When using the couch, the section represented in red (see Figure 7-3) is not part of
the treatment volume.
The dimensions of the rectangular sides of the triangle are as follows:
 +/- 0° pitch: 5 cm by 5 cm
 +/- 5° pitch: 10 cm by 10 cm
1. To establish whether or not the table-top offers uniformity, refer to the OEM
documentation.
WARNING Due to existing interferences, it may not be possible to acquire images
of certain points of the treatment volume in all hardware
configurations. You must select the proper arm configuration (right or
left) such that the oblique imager X-ray beams will not be obstructed by
the robotic arms.
