Field output factors for small fields: A large multicentre study

Small field dosimetry remains a challenging discipline and determination of field output factors is essential when implementing stereotactic radiotherapy. In 2017, the International Atomic Energy Agency (IAEA) published Technical Reports Series no. 483 (IAEA TRS-483) [1] providing recommendations for small field measurements and values of correction factors (kQclin,Qmsrfclin,fmsr) to apply to the ratio of detector readings (MQclinfclinMQmsrfmsr) which allow the determination of the field output factor ( ΩQclin,Qmsrfclin,fmsr).
