13. Automatic Detection of Common Signal Quality Issues in MRI Data using Deep Neural Networks
University essay from Linköpings universitet/Institutionen för medicinsk teknikAbstract : Magnetic resonance imaging (MRI) is a commonly used non-invasive imaging technique that provides high resolution images of soft tissue. One problem with MRI is that it is sensitive to signal quality issues. The issues can arise for various reasons, for example by metal located either inside or outside of the body. READ MORE

15. CHARACTERIZATION AND EVALUATION OF A NIPAM POLYMER GEL MRI DOSIMETER SYSTEM
University essay fromAbstract : Purpose: The normoxic polymer gel dosimeter based on N-isopropyl acrylamide (NiPAM) is a promising full 3D-dosimeter with high spatial resolution and near tissue equivalency. However, limited work have been done in vestigating this dosimeter. The dose response and reproducibility of a NiPAM dosimeter was investigated. READ MORE
