Remarks
Entrance and/or exit dose in vivo dose measurements still a valid method
for QC of the delivered dose at one point
Limitations of point detectors on the surface of the patient for IMRT
techniques, SBRT…
Need of solutions:
Implantable detectors (point dose inside the
area of interest)
EPIDs (2D information, labour intensive,
need
of dose calculation algorithms)
Transmission chambers+conebeam CT
[need
of dose calculation algorithms]
NEED TO KNOW THE DELIVERED AND NOT THE PLANNED
DOSE TO EVALUATE THE SUCCESS OF A TREATMENT.
