Conclusions
•
Brachy plan must be evaluated using
point doses
(in some
cases),
DVH
parameters,
dose distribution
and global
indexes.
•
Overdose volumes due to
“target points”
based optimization
must be
carefully evaluated
(more convenient “basal points”).
•
Resulting
under-over dose
volumes must be evaluated looking
in detail at the
3D
dose distribution.
•
For small volumes
whole
OAR volume subrogates well to the
wall
.
•
Sampling and
histogram
bar with must be selected with
high
resolution.
•
EQD2
evaluation in cervix GYN
needs
an adequate
implementation on TPSs future versions by manufacturers in
order
to improve efficiency
.
