Photon and electron backscatter dose and energy spectrum analysis around Lipiodol using flattened and unflattened beams

摘要

PurposeThe aim of the current study was to evaluate the backscatter dose and energy spectrum from the Lipiodol with flattening filter (FF) and flattening filter‐free (FFF) beams. Moreover, the backscatter range, that was defined as the backscatter distance (BD) are revealed.
