Film dosimetry was the standard for 2D dose measurements.
BUT Trends towards so called “digital hospitals”
•
No access to film processing machine
Wish to implement fast
real-time
procedures for measurements
2D: Detector arrays
2D detector arrays are an option
•
No necessity to downscale MUs to the sensitive range (not for EBT- XT)
•
Potential for absolute dose measurements
•
Results available immediately after irradiation
•
Mostly limited to single beam verification
