Advances in real-time phase-contrast flow MRI and multi-echo radial FLASH
(2016-05-26)The conventional multi-echo radial fast flow angle shot (FLASH) utilizes bipolar readout gradients with the same amplitude and duration to sample echoes in a fly-back-and-forth manner. This strategy is inefficient with ... -
An Exploration of Real-Time Functional Magnetic Resonance Imaging Neurofeedback in Cognition
(2014-10-31)This thesis deals with an extensive exploration of the use of rt-fMRI neurofeedback in cognition. Specifically, the work presented here comprises the major steps in the development of a suitable experimental framework for ... -
Development of Advanced Acquisition and Reconstruction Techniques for Real-Time Perfusion MRI
(2017-01-09)This thesis concentrates on methodological developments in both acquisition and reconstruction techniques when applying concepts from real-time imaging to the field of dynamic contrast-enhanced magnetic resonance imaging. ... -
Dynamic Temperature Mapping - Real-time Strategies and Model-based Reconstructions
(2017-02-09)The purpose of this thesis was to explore the potential of real-time MRI methods for temperature mapping during thermal procedures. This mainly included a comprehensive analysis of two different methods, i.e. proton resonance ... -
Multi-Directional Phase-Contrast Flow MRI in Real Time
(2021-01-28)This work describes the development of a phase-contrast MRI technique that achieves multi-directional velocity quantification in real time, i.e. at high spatio-temporal resolution and without any physiological gating or ... -
On the Use of Temporal Information for the Reconstruction of Magnetic Resonance Image Series
(2020-10-28)Standard clinical magnetic resonance imaging uses data sampled at the Nyquist rate which limits it to frame rates of 1-4 frames per second. Over the past decade different methods for the reconstruction of images from ... -
The role of human medial frontal cortex in cognition investigated by functional magnetic resonance imaging.
(2007-11-22)In my PhD research project I have used functional magnetic resonance imaging (fMRI) to investigate the functional anatomy of human medial frontal cortex (MFC) during performance of three ... -
The somatosensory system: Exploration of digit-area somatotopy and feature-based attention
(2013-12-19)Even though the skin is by far the largest sensory organ that we humans possess and immensely important for coping with everyday life, the somatosensory system has been studied far less than the visual or auditory system. ... -
Undersampled Radial STEAM MRI: Methodological Developments and Applications
(2018-03-09)The diffusion-weighted (DW) single-shot stimulated echo acquisition mode (STEAM) sequence offers DW MRI without susceptibility artifacts which severely hamper diagnostic applications when using conventional echo-planar ...
