How the UBTI Affects the Irradiation Process
The UBTI operates differently with each of the treatment modes, as follows:
 Pencil Beam Scanning: refer to Section “Using UBTI in the Pencil Beam
Scanning Treatment Mode” on page 48-18.
Using UBTI in the Pencil Beam Scanning Treatment
Mode
Gating system screen (e.g. gateRT screen)
adaPTdeliver screen
Status lamp on gating system hardware (e.g. gateRT gating controller)
Status lamp on UBTI console (Beam On Trigger lamp)
Status lamp on imaging booth UBTI box
CAUTION As a Radiation Therapy Technologist, when planning a treatment with
automatic beam gating, choose the treatment delivery settings (such as
beam delivery technique, dose rate, number of repaintings) and patient
monitoring settings (such as duty cycle, acquisition frequency) in
function of the clinical goals to be achieved and safety criteria to be
met, taking into account the global latency of the system (latency of the
patient monitoring system combined with the latency of the treatment
machine and the latency to detect and process a system failure).
