1. Diffusion MRI with generalised gradient waveforms : methods, models, and neuroimaging applications
Abstract : The incessant, random motion of water molecules within biological tissues reveals unique information about the tissues’ structural and functional characteristics. Diffusion magnetic resonance imaging is sensitive to this random motion, and since the mid-1990s it has been extensively employed for studying the human brain. READ MORE

2. Non-invasive Functional Neuroimaging for Localizing Epileptic Brain Activity
Abstract : Surgical therapy has become an important therapeutic alternative for patients with medically intractable epilepsy. Correct and anatomically precise localization of the epileptic focus, preferably with non-invasive methods, is the main goal of the pre-surgical epilepsy diagnosis to decide if resection of brain tissue is possible.

3. Deep learning on large neuroimaging datasets
Abstract : Magnetic resonance imaging (MRI) is a medical imaging method that has become increasingly more important during the last 4 decades. This is partly because it allows us to acquire a 3D-representation of a part of the body without exposing patients to ionizing radiation. READ MORE

4. Blood flow assessment in cerebral arteries with 4D flow magnetic resonance imaging : an automatic atlas-based approach
Abstract : Background: Disturbed blood flow to the brain has been associated with several neurological diseases, from stroke and vascular diseases to Alzheimer’s and cognitive decline. To determine the cerebral arterial blood flow distribution, measurements are needed in both distal and proximal arteries. READ MORE

5. On-scalp MEG using high-Tc SQUIDs: Measuring brain activity with superconducting magnetometers
Abstract : This thesis describes work done towards realizing on-scalp magnetoencephalography (MEG) based on high critical temperature (high- T c) superconducting quantum interference device (SQUID) sensors. MEG is a non-invasive neuroimaging modality that records the magnetic fields produced by neural currents with good spatial and high temporal resolution. READ MORE
