A Comparison of Biological Dose Estimates in Proton and Carbon Ion Therapy Based on Averaged and Full Linear Energy Transfer Spectra
(Master thesis, 2015)Radiotherapy with ions, also known as particle therapy, is increasing rapidly. Shifting from photons to protons and carbons is not only a great technological transition, but also a shift in physics and in radiobiology. ... -
Acoustic Cluster Therapy in the chicken chorioallantoic membrane model
(Master thesis, 2018)In this thesis the chicken chorioallantoic membrane (CAM) model was used to study the enhanced delivery of intravenously injected \SI{2}{\mega\dalton} FITC-dextrans using ultrasound in combination with microbubbles. An ... -
Adaptive Clutter Filtering for Improved Measurement of Cardiac Blood Velocities
(Master thesis, 2017)In ultrasound color flow images of the heart, irregular blood flow patterns might be an early indication of heart disease. The blood flow is possible to image using multi-dimensional blood velocity estimation like speckle ... -
Classification of Breast Cancer Based on DCE MRI
(Master thesis, 2017)This master thesis is a part of a project at the MR group at the department of physics at NTNU. The aim of MR group is to make a model which is able to classify the subtype of breast tumours. In this master thesis the focus ... -
Comparison of two diffusion weighted MR protocols for detecting Differences in Microvasculature in chronic Pancreatitis and Pancreas Cancer
(Master thesis, 2016)Pancreatic cancer is a type of cancer with high mortality. Unspecific, or the absence of, symptoms result in late diagnosis, which is fatal when the only curable treatment is surgical removal of the tumor. Differentiating ... -
Development of a Smartphone-based diagnostic Tool for Jaundice
(Master thesis, 2014)Jaundice is the cause of an estimated 114,100 deaths among newborn annually. Most of these deaths occur in the poorest regions of the world where current diagnostic technologies are too expensive. In this thesis, several ... -
Dose surface maps as a tool to predict toxicity after radiotherapy for cervical cancer patients
(Master thesis, 2017)Cervical cancer is one of the leading cancer types for women, both in incidence and mortality. The standard treatment for cervical cancer is brachytherapy and external beam radiotherapy in combination with chemotherapy. ... -
Effect of Glutaminase Inhibition in Basal-Like Patient-Derived Xenografts Analyzed by Magnetic Resonance Spectroscopy
(Master thesis, 2017)Breast cancer is today the leading cause for cancer related deaths among women in Europe. Decreased mortality among breast cancer patients has been observed over the last twenty years, where development and use of targeted ... -
The effect of macromolecular crowding with polyanions on DNA condensation
(Master thesis, 2018)The condensation of DNA induced by the cationic surfactant CTAB was investigated in the presence of the negatively charged macromolecule PAMAM. Surprisingly, PAMAM promotes rather than inhibits condensation, as opposed to ... -
Electrical Bioimpedance Based Heart Monitoring System
(Master thesis, 2016)There is a great need for monitoring devices in the intensive care unit during, and after, cardiac surgery to be able to detect anomalies at an early stage. The techniques used today are good, but limited in di erent ways. ... -
The Establishment of an Intravoxel Incoherent Motion Based MRI-Protocol for Differentiation of Focal Lesions in the Pancreas
(Master thesis, 2015)The mortality related to pancreatic cancer is high. It spreads rapidly and as the situation is today it is often not diagnosed until a quite late stage. However, recent studies have shown that the intravoxel incoherent ... -
Evaluation of Robustness in Volumetric Modulated Arc Therapy (VMAT) plans for Head and Neck Cancer Patients
(Master thesis, 2017)Purpose: To investigate the robustness of volumetric modulated arc therapy (VMAT) plans for head and neck (H&N) cancer patients. Methods and materials: The patient population consisted of 15 patients with H&N cancer having ... -
Implementation and Application of Method for Differential Correlation Network Analysis.
(Master thesis, 2017)A novel framework for differential co-expression networks have recently been developed at the Department of Biotechnology and Food Science at the Norwegian University of Science and Technology (NTNU). The method, referred ... -
Implementation of geometric distortion correction of EPI images in clinical workflow
(Master thesis, 2018)Background: Geometric distortion in echo-planar (EPI) magnetic resonance (MR) images, caused by low bandwidth combined with variations in magnetic susceptibility, is a problem that can make it challenging to connect ... -
Intracellular Localization of Polymeric Nanoparticles and the Effect of Encapsulated Drug in vitro
(Master thesis, 2015)Chemotherapy could be greatly improved if drug carriers could deliver the chemotherapeutic agents specifically to the cancer cells. SINTEF Materials and Chemistry have developed a novel, multimodal polymeric nanoparticle ... -
Intraventricular Vector Flow Mapping ― An In Silico and In Vivo Evaluation
(Master thesis, 2018)Modern cardiology research aims to encompass sophisticated analysis of intraventricular blood flow in the clinical practice. Such analysis relies on robust and effective means of measuring blood flow fields, an approach ... -
Kinetic Modelling of Dynamic Contrast-Enhanced MR Images: Impact of the Arterial Input Function
(Master thesis, 2018)The standard treatment of rectal cancer is surgery, and in locally advanced cases, neoadjuvant chemoradiotherapy (CRT). By obtaining knowledge about the aggressiveness of tumours prior to treatment, the treatment can be ... -
Magnetic Resonance Imaging: Multidimensional non-Gaussian Diffusion-weighted MRI - Image quality analysis
(Master thesis, 2015)To investigate the viability of two different nuclear magnetic resonance imaging systems for acquisition of highly diffusion weighted, multidimensional human brain data, images were acquired on both, using two different ... -
Mechanical and Acoustic Characterization of Perfluorocarbon Microbubbles Containing Nanoparticles
