UBTI Details
Specific types of treatment and tumors may require specific types of gating
equipment to monitor physiological motions. The UBTI therefore caters to four
distinctive gating devices that can remain connected to the Universal Triggering
Electronic Unit (UTEU) rack at any given time. In this way gating equipment can
remain installed in the TR, without a need to reinstall and reconnect other gating
equipment.
The UTEU enables the RTT to switch between various types of physiological cycle
measuring devices and the use of the resulting triggering signal for patient
positioning verification and for irradiation with the proton beam.
Explaining the Universal Beam Triggering
Interface
Location
The UBTI is accessible through the UTEU, which is the rightmost module of the
Safety and Triggering rack in the TCR.
Figure 48-1. UTEU Rack
(as part of the Safety and Triggering Rack)
Up to four distinctive gating systems can simultaneously remain connected to the
UTEU rack. The X-ray generator is also connected to the rack in order to trigger the
X-ray beam.
In addition, the UTEU rack is connected to the BGEU, which interfaces with the
following:
 Scanning Controller: for Pencil Beam Scanning
 UTEU rack: to receive triggering information
