1. 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.

2. Verification measurements on MRI-linac with PTW BEAMSCAN MR
University essay from Umeå universitet/Institutionen för fysikAbstract : In radiotherapy the main goal is to kill cancer cells, prevent them from growing and reproducing, while healthy tissue is spared. One technique to treat cancer is to use external radiotherapy where a linear accelerator (linac) is used to generate a high energy radiation photon beam. READ MORE
