Abstract: Photon beams with wide energy ranges from 4 MV to 25 MV are commonly used in radiotherapy nowadays. In recent years, there has been a strong interest in a certain modifi cation of a radiotherapeutic apparatus by the application of the so-called fl attening fi lter-free (FFF) beam. Several advantages of FFF beams over standard fl attening fi lter (FF) beams are noticed, and this technical solution has aroused great interest among radiotherapeutic facilities. The goal of the present study is to investigate the differences between the conventional FF and unfl attened FFF 6-MV and 10-MV photon beams in some basic dosimetric parameters and their infl uence on the whole radiotherapeutic treatment. The data provided here include the detailed characteristics as follows: percent depth dose (PDD), beam profi le, edge of a half-profi le, total scatter correction factor (TSCF) and head scatter correction factor (HSCF) for FF and FFF 6-MV and 10-MV photon beams from the Elekta Versa HD accelerator in the Katowice Oncology Center in Poland.
