When gating is not required, only “NO” may be selected on the UTEU rack.
Prescription display
The gating information is displayed in the header part of the screen.
When a plan or setup beam is selected, the prescription at plan level is displayed and
can be:
 GATING: Yes, or
 GATING: No, or
 GATING: Mixed (in case individual treatment beams have different
prescriptions).
When a treatment beam is selected, the prescription at beam level is displayed and
can be:
 GATING: Yes, or
 GATING: No
Prescription mismatch
As soon as the setup beam is selected, if gating is prescribed at plan level, the PTS
will warn you if no gating input is selected (selector in position NO), and prevent the
preparation of the beam. This ensures that the gating system is set up when the
patient is aligned on the table (Figure 48-3).
