A review on radiochromic film dosimetry for dose verification in high energy photon beams

A dosimetry system composed by Gafchromic™ EBT films and a flatbed document scanner is a valuable tool for patient-specific quality assurance (QA) of complex external beam radiotherapy treatment plans. However, it is still not widely used in clinical practice. The need for a comprehensive characterization of the film-scanner performance and the establishment of a complex dosimetry protocol may be one of the causes of this weak adhesion. The...
