    University essay from Umeå universitet/Institutionen för fysik

    Author : Erik Nilsson; [2019]
    Keywords : Deep learning; convolutional neural networks; CNN; super-resolution; MRI;

    Abstract : There are many clinical situations where magnetic resonance imaging (MRI) is preferable over other imaging modalities, while the major disadvantage is the relatively long scan time. Due to limited resources, this means that not all patients can be offered an MRI scan, even though it could provide crucial information. READ MORE
