Small field correction factors for the IBA Razor

Small field correction factors for the IBA Razor

Highlights • The IBA Razor overresponds in small fields as with other silicon diodes. • Correction factors for the overresponse are presented for Varian linacs. • The correction factor of FF beams was compared to that of FFF beams. • The overresponse can be predicted mathematically based on the fiel...
