3D-EPI with parallel imaging acceleration along two Axis: Evaluated with Phantom Study and BOLD fMRI
Vaksdal, Martin (Master thesis, 2013)The function of the human brain has for many years been an intriguing field of research, and has led to the discovery of functional MRI (fMRI). fMRI is dependent on high spatial and temporal resolution to acquire detailed ... -
Data acquisition for high resolution blood oxygen level dependent fMRI
Ladstein, Jarle (Doctoral theses at NTNU;2018:75, Doctoral thesis, 2018)Blood oxygen level dependent functional magnetic resonance imaging (BOLD fMRI) is an important non-invasive technique for investigation of brain function. Using BOLD fMRI, brain activity can be localized with high spatial ... -
Dynamic Micro-CT utilising Golden Ratio Sampling and Three-dimensional Generative Adversarial Networks
Dragland, Ruben Skjelstad (Master thesis, 2023)Temporal datatomografi, dynamisk datatomografi, eller bare 4D-CT, er en røntgenavbildningsteknikk hvor tredimensjonale dynamiske prosesser kan avbildes. Ulempen med CT er de mange projeksjonene som kreves for å rekonstruere ... -
Effect of task-correlated physiological fluctuations and motion in 2D and 3D echo-planar imaging in a higher cognitive level fMRI paradigm
Ladstein, Jarle; Evensmoen, Hallvard Røe; Håberg, Asta; Kristoffersen, Anders; Goa, Pål Erik (Journal article; Peer reviewed, 2016)Purpose: To compare 2D and 3D echo-planar imaging (EPI) in a higher cognitive level fMRI paradigm. In particular, to study the link between the presence of task-correlated physiological fluctuations and motion and the fMRI ...
