healthy tissue. The surge in related medical research activities over the last couple of years has triggered a
demand for technology with the capability of generating and measuring ionizing radiation at ultra-high doserates (UHDR). A reliable dosimetry system is an integral part of a radiotherapy machine. Because existing active
dosimetry methods are unable to handle the dose-rates required for FLASH, UHDR dosimetry has emerged as an
important area of research. In this paper we present an active dosimetry method based on a scintillating screen
and an integrating current transformer. This method provides a simultaneous measurement of the absolute
dose delivery as well as the 2D dose distribution. The measurements have been correlated with corresponding
readings from radiochromic films (RCFs), and a procedure for image processing has been established. Moreover,
different methods of calibrating the active dosimetry system against RCFs have been introduced and evaluated.
Lastly, we present results which demonstrate that an agreement with RCFs of better than 5% can be realistically
expected if camera parameters are carefully optimized.
