Imaging Dose Evaluation of the Varian Probeam CBCT Using Radiophotoluminescent Glass Dosimeters

Accurate patient positioning is critical in proton therapy, where range uncertainties increase sensitivity to setup errors; therefore, cone beam computed tomography (CBCT) is routinely used for image guidance. However, it also increases radiation dose to norm...

Evaluation of Radiation Dose to Thoracic Organs from 3D Versus 4D CBCT Using Radiophotoluminescent Glass Dosimeters

Four-dimensional cone-beam computed tomography (4D-CBCT) provides respiratory motion–resolved imaging for image-guided radiotherapy (IGRT) in thoracic treatments but may increase imaging dose compared with conventional three-dimensional CBCT (3D-CBCT). This s...
