If we set up a prostate patient daily using ultrasound
(or cone beam CT with fiducials),
what should we do with the compensator of a lateral proton beam
passing through the femoral head ?
-
Mitigate
as much as possible the mouvement (baloon, blader filling, others…)
-
Daily images
of bony and soft tissues (or fiducials)
-
Fix the compensator
to the set up done to the bony structures (X rays, CBCT,…)
-
Use the residual ITV
(Internal Target Movement)
to calculate & smear the compensator
-
Survey online
the set up & intrafraction movement into tolerences (calypso, scopie,…)
-
Evaluate & optimise the dosimetric effects in any approach
-(and possibility to use MLC, patient positioner, others… to conform or track…?)
- AND ADAPT !
