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.

3. Validation of a method utilising MR images for dose planning of prostate cancer treatment : Validation of new coil technology applied on the pelvis region of healthy volunteers
University essay from Linköpings universitet/Institutionen för hälsa, medicin och vårdAbstract : By generating a synthetic CT image (sCT) directly from the MRI, the electron density can be calculated, and the CT examination can be excluded from the patient flow minimizing the risk of uncertainties in the registration. Basing the radiation treatment process solely on MR images is called MRI-only and is beneficial for the patient as it can provide more accurate radiation treatment than the standardised treatment with fewer CT examinations and possibly a more cost-effective radiation treatment process.

5. Verification Testing of Evacuationz, a Coarse Network Evacuation Model
University essay from Lunds universitet/Avdelningen för BrandteknikAbstract : Several evacuation models exist in the market. It is an issue for both the user and developer to evaluate the ease of use and the quality of the model results. Verification is the process of determining that the results of a calculation method match with the developer's conceptual modelling representation expectations, i.e. READ MORE
