Finally: Some (more) words of caution
•
Deformable registration errors => dose warping errors!
Deformable registration is especially challenging for prostate/rectum
•
Thus: Are hot/cold spots in an accumulated dose real? Should these be
actively compensated for?
•
Dose calculation on cone beam CT data: no high-precision dose
calculation possible, thus dose-of-the-day calculation is subject to
errors
The ‘latest-and-greatest’ ART schemes use methods from the
‘toolbox’, that start to find its way into commercial products
and thus into clinical practice.
BUT be aware…
