2. Uncertainties in the use of synthetic CT (sCT) for daily online adaptive radiotherapy for lung cancer
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Background and purpose: Cone Beam Computed Tomography (CBCT) based online adaptive radiotherapy (oART) has been clinically implemented for several anatomical sites worldwide. However, random and abrupt anatomical changes with large density alterations can occur in lung patients, leading to uncertainties with synthetic computed tomography (sCT) and dose calculation.
