Target volumes – overlaps

There are always occasions when the PTV and OARs/PRVs  overlap What is the best strategy?

The planning concept has changed between ICRU 62 and 83 …..  In fact changed  completely in ICRU 83

ICRU 62 – edit PTV (even CTV) – fine for CRT ICRU 83 – do not edit – better for IMRT
