EPID as 2D Detector

Trends towards so called “digital hospitals” • No access to film processing machine • Film dosimetry limited to radiochromic films

Wish to implement fast real-time procedures for measurements

EPID are an option

No necessity to downscale MUs to the sensitive range

Potential for absolute dose measurements

Results available “immediately” after irradiation

Mostly limited to single beam verification

Good spatial resolution

Need of corrections to convert the resulting signal into fluence or dose in detector
