The aim of this study was to determine small field correction factors for a synthetic single-crystal diamond detector (PTW microDiamond) for routine use in clinical dosimetric measurements.Correction factors following small field Alfonso formalism were calculated by comparison of PTW microDiamond measured ratio MQclinfclin/MQmsrfmsr with Monte Carlo (MC) based field output factors ΩQclin,Qmsrfclin,fmsr...
We investigated the volume averaging effect for air-filled cylindrical ionization chambers to determine the correction factors in a small photon field for a given chamber. We measured output factors with several cylindrical ionization chambers, and by using a mathematical method similar to deconvolution, we modeled the non-constant and inhomogeneous exposure function in the cavity of the chamber...
