An
independent calculation of monitored units
(iMUc) is supposed
to verify that the treatment planning system (TPS) is an accurate part of the
complex system for the delivery of a safe and effective treatment.
Planning systems are subjected to rapid evolution, they implement new
complex technologies and therefore it is
not possible to verify all
potential future clinical usage
in advance.
Many factors, such as layout of anatomic structures, positioning of a
patient, factors related to an accelerator (a dose calibration and mechanic
parameters)
cause random and systematic failures
in a dose delivery.
The source of some problems can be also caused by the
system databases
and relating information transfer
; and the TPS containing besides
other things other dose calculation algorithms.
Legislation
requires iMUc in many countries.
