Evaluation of Radiation Dose and Image Quality for the Varian Cone Beam Computed Tomography System

Purpose To compare the image quality and dosimetry on the Varian cone beam computed tomography (CBCT) system between software Version 1.4.13 and Version 1.4.11 (referred to as “new” and “old” protocols, respectively, in the following text). This study investigated organ absorbed dose, total effectiv...
