Dose Course 2018_Flipping book

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.
