MR image quality assessment of a radiotherapy tailored imaging setup on hybrid PET/MRI: a phantom study
Bratting, Ole Jakob Berg (Master thesis, 2022)Utviklingen av kombinerte medisinske avbildningssystemer kan fobedre stråleterapibehandling ved å forbedre presisjonen i inntegningen av kreftsvulster og identifiseringen av aggressive områder innad i svulsten. En scanner ... -
MR-based radiotherapy dose painting: modelling studies
Julbø, Frida Marie Ihle (Master thesis, 2020)Bakgrunn: Effekten av kjemoradiasjonsterapi (CRT) hos pasienter med endetarmskreft er svært varierende, og er avhengig av aggressiviteten til tumoren. Tumoren bestråles vanligvis med en uniform dosefordeling, selv om de ... -
MRI-based automatic segmentation of rectal cancer using 2D U-Net on two independent cohorts
Knuth, Franziska Hanna; Adde, Ingvild Askim; Huynh, Bao Ngoc; Groendahl, Aurora Rosvoll; Winter, René Mario; Negård, Anne; Holmedal, Stein Harald; Meltzer, Sebastian; Ree, Anne Hansen; Flatmark, Kjersti; Dueland, Svein; Hole, Knut Håkon; Seierstad, Therese; Redalen, Kathrine Røe; Futsaether, Cecilie Maria (Peer reviewed; Journal article, 2022)Background: Tumor delineation is time- and labor-intensive and prone to inter- and intraobserver variations. Magnetic resonance imaging (MRI) provides good soft tissue contrast, and functional MRI captures tissue properties ... -
MRI-Based Radiomics Analysis for Predicting Treatment Outcome in Rectal Cancer
Langan, Aase Mellingen (Master thesis, 2020)Med et ønske om å bidra til forskningen om hvorvidt radiomics-parametre fra MR-bilder kan være biomarkører for endetarmskreft, hadde denne oppgaven tre hovedmål. For det første, å etablere og optimalisere binære ... -
Next-generation sequencing reveals mitogenome diversity in plasma extracellular vesicles from colorectal cancer patients
Bjørnetrø, Tonje; Bousquet, Paula; Redalen, Kathrine Røe; Siebke, Anne-Marie; Lüders, Torben; Stang, Espen; Sanabria-Moreno, Adriana Maria; Johansen, Christin; Fuglestad, Anniken Jørlo; Kersten, Christian; Meltzer, Sebastian; Ree, Anne Hansen (Peer reviewed; Journal article, 2023)Background Recent reports have demonstrated that the entire mitochondrial genome can be secreted in extracellular vesicles (EVs), but the biological attributes of this cell-free mitochondrial DNA (mtDNA) remain ... -
Photon attenuation correction of radiotherapy-specific prostate and head/neck hardware components in combined PET/MRI
Wivilson, Linnea (Master thesis, 2021) -
Preclinical studies of Cu-64 radiopharmaceuticals for theranostics of hypoxic tumors
Dahle, Maria Aanesland (Master thesis, 2021)Abstract will be available on 2024-08-26 -
Professional practice changes in radiotherapy physics during the COVID-19 pandemic
Bertholet, Jenny; Aznar, Marianne C.; Garibaldi, Cristina; Thwaites, David; Gershkevitsh, Eduard; Thorwarth, Daniela; Verellen, Dirk; Heijmen, Ben; Hurkmans, Coen; Muren, Ludvig; Redalen, Kathrine Røe; Siebert, Frank-André; Schwarz, Marco; Van Elmpt, Wouter; Georg, Dietmar; Jornet, Nuria; Clark, Catharine H. (Peer reviewed; Journal article, 2021)Background and purpose The COVID-19 pandemic has imposed changes in radiotherapy (RT) departments worldwide. Medical physicists (MPs) are key healthcare professionals in maintaining safe and effective RT. This study ... -
Radiation dose and image quality in CT - Comparison and evaluation of two different organ-based tube current modulation techniques and their impact on organ dose and image noise
Rekdal, Anna Lovise (Master thesis, 2019)Bakgrunn: Computertomografi (CT) -undersøkingar er eit mykje brukt vertøy i medisinsk dignostikk, og bruken aukar. Denne auka har først til auka uro over stråledosen pasientar blir utsett for. Det er viktig å optimalisere ... -
Radiation dose and image quality in CT - Evaluation of how slice thickness, tube current modulation and reconstruction algorithms affect radiation dose and image noise
Guleng, Marte Anette Dunseth (Master thesis, 2018)Background: Helse Vest has currently standardized the computed tomography (CT) Thorax/Abdomen/Pelvis protocols in the region. One of the standardized parameters was a reduction of the reconstructed slice thickness from 5 ... -
Radiotherapeutic Limits of Acceptance for Errors in Synthetic CT Synthesised from MRI
Jensen, Leif-André Bjerkeli (Master thesis, 2020)CT-skanninger, som resulterer i elektrontetthetskart eller massetetthetskart, er standard inndata for strålebehandlingplanleggingssystemer. Imidlertid gir MR overlegen bløtvevskontrast. I tilfeller der MR er nødvendig for ... -
Streamlining the use of PET/MRI in an MR-only radiotherapy workflow
Bach-Gansmo, Nina Ingeborg (Master thesis, 2021) -
Tumor segmentation by deep learning
Skjelbred, Eline Furu (Master thesis, 2020)Et viktig steg i både kvantitativ bildeanalyse og strålebehandling er inntegningen av kreftsvulstvolumet. Dette er en tidkrevende oppgave, og det er den største kilden til usikkerhet grunnet interobservatørvarabilitet. ...
