  4. 3. MRI Signals Simulation for Validation of a New Microvascular Characterization

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Aurélien Delphin; [2019]
    Keywords : MRI; fingerprinting; simulations; MRVox2D;

    Abstract : Conventional MRI techniques are not convenient when it comes to study cerebral microvascularization due to the length of the scans needed. A technique called Magnetic Resonance Fingerprinting (MRF) is an excellent candidate to solve this problem as it requires much shorter scan durations. READ MORE
