Microfluidics for Biological Studies - A Double Emulsion Platform for Cell Encapsulation and Analysis
(Master thesis, 2016)Encapsulation of biologicalmaterial in small, confined volumes has enabled the study of individual cells, revealing valuable and detailed information on cellular processes and behavior unavailable in traditional bulk ... -
Monte Carlo simulations to probe gel-nanoparticle interfaces using restricted polymers to mimic surface topologies
(Master thesis, 2018)The use of silica nanoparticles as an adhesive mediator in hydrogels and suturing of wounds, has been of interest. This thesis investigates the mode of interaction between nanoparticles and a polymer network interface, ... -
Multi-Target Stereotactic Brain Radiation Therapy
(Master thesis, 2018)Metastasis of the brain is one of the most common and severe neurological complications of cancer. Stereotactic radiation therapy (SRT) characterized by a high dose of radiation, delivered in a single or few fractions, ... -
Nanoparticles for Wound Closure
(Master thesis, 2018)Studies have shown the potential of the application of nanoparticles in wound closure. In some cases, the nanoparticles have shown to aggregate in the wound, delaying the natural healing processes, which involve cell ... -
Optimal threshold for PET-based autocontouring of boost volume for radiotherapy of anal carcinoma
(Master thesis, 2017)For patients with anal carcinoma, local tumor control and local recurrence after radiotherapy treatment is a challenge. To improve the local control, a dose escalation could be delivered. Using FDG-PET, the most glucose-avid ... -
Optimization and verification of dosimetric robustness of VMAT dose-plans
(Master thesis, 2016)Radiation therapy has for several years played an important role in the curative management of patients with early stage disease and also in the palliation of symptoms associated with advanced or metastatic disease. Organs ... -
Optimization of volumetric modulated arc therapy of cervical cancer - Retrospective treatment planning for simultaneous integrated boost, with and without flattening filter
(Master thesis, 2018)The traditional treatment of cervical cancer is external beam radiotherapy (EBRT) combined with brachytherapy (BT) and concomitant chemotherapy. BT is used to boost the primary tumor in the pelvic area towards the end of ... -
Protein Binding and Crowding Effects on DNA Condensation
(Master thesis, 2015)The main goal of this work is to map how bacterial nucleoid associated proteins (NAPs) condense DNA in tandem with a crowded environment, since this may provide useful information for research where DNA compaction and ... -
Proton therapy of head and neck cancer: evaluation of PTV-based and robust optimized IMPT versus VMAT
(Master thesis, 2017)Radiation therapy for head and neck cancers has had an essential role for curative treatment for many years. Due to the location of the cancer, several critical organs will get irradiated and this may lead to serious ... -
Quantitative Comparison of PET/MR and PET/CT for Imaging of Lymphoma Patients
(Master thesis, 2015)Positron emission tomography/computed tomography (PET/CT), a multimodality imaging tool, is today the golden standard in diagnosis, staging and response monitoring of lymphoma patients, while it is investigated if positron ... -
Robot Control in Image-Guided Intervention
(Master thesis, 2016)Introducing autonomous robot systems in clinical medicine is deemed extremely challenging due to the complex scene involved and variations between patients. The majority of commercialized systems are controlled directly ... -
Stereotactic Radiation Treatment of Lung Cancer by VMAT.
(Master thesis, 2015)Radiotherapy of early stage non-small cell lung cancer (NSCLC) is a challenging treatment due to the varying tissue densities in the irradiated volume and the moving target. At Haukeland University Hospital (HUH) the ... -
Study of the chicken chorioallantoic membrane (CAM) as an in vivo-model for ultrasound-mediated delivery of drugs using nanoparticle-stabilized- and standard ultrasound microbubbles
(Master thesis, 2018)The chick chorioallantoic membrane (CAM) model has been widely used in the fields of biology and medicine, and it provides a good in vivo model for studying vascularisation properties of a developing chicken embryo. The ... -
Study of water self-diffusion in healthy fibroglandular breast tissue
(Master thesis, 2017)Magnetic resonance imaging (MRI) is an important imaging modalty available in modern medical diagnostics. Novel MR scanner software made available from the vendor was implemented on a clinical MR-scanner. MR measurements ... -
The Influence of the Energy Degrader Material for a Therapeutical Proton Beam
(Master thesis, 2015)In cyclotron based proton therapy an energy degrader is needed to modulate the proton beam energy. The proton beam energy decides the range of the particles and thereby where the dose is imparted. The influence of the ... -
Towards minimizing variations in the comet assay: The electric potential during electrophoresis and implications of circulating the electrophoresis solution
(Master thesis, 2016)The comet assay (single cell gel electrophoresis) is a sensitive and versatile technique for measuring DNA damage and repair at the single cell level. Östling and Johanson were the first to introduce the comet assay in ... -
Treatment Planning for External Beam Radiation Therapy with Simultaneous Integrated Lymph Node Boost in Cervical Cancer
(Master thesis, 2018)Cervical cancer with lymph node metastases has traditionally been treated with external beam radiation therapy (EBRT) to a large pelvic target volume followed by a sequential boost to the affected lymph nodes, and brachytherapy ... -
