  1. 1. Reduction of Noise and Artefacts in MRIScan of Metal Implant Reconstructed by Frequency Mapping

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Pontus Wahlqvist; [2022]
    Keywords : Technology and Engineering;

    Abstract : Metal objects can cause significant artefacts in magnetic resonance imaging (MRI) scans, cause loss of signal and what is known as geometric warping. There are ways to address these problems using different MRI sequences. This project looks at a newer method of artefact correction proposed by Månsson and Morin. READ MORE
