Evaluation of dosimetric impact of Flattening Filter-Free (FFF) Photon Beams in 3D conformal radiotherapy
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 1
Abstract
Flattening Filter Free (FFF) photon beams have been frequently used in radiotherapy clinical practice. This study aimed to analyze the dosimetric quality of the FFF beams, as compared to the standard flattened beams (FB) for plans of treatment of three patients involving three cancer sites using the 6 and 10 MV photon energies and the 3D conformal radiotherapy technique (3D-CRT). The doses to the planning target volumes (PTVs) and organs at risk (OARs) were compared. The dose-volume histogram curves analysis show that no significant differences between FFF and FB plans were found in the coverage and mean dose for the PTV, the OAR revealed slight differences. So the FFF photon beam achieved comparable dosimetric quality as the standard flat beam.
