    Sammanfattning : This paper consists of a literature study and laboratory experiments of magnesium oxide boards, from Swedish suppliers, that is a part of a larger research project. Lately the boards have become known for the way they absorb moisture which has led to damage on adjacent materials. The boards are inorganic and are marketed as moisture proof. LÄS MER

    Sammanfattning : Noise is a well-known problem in many imaging modalities. In magnitude magnetic resonance images, obtained by quadrature detection, the associated Rician distribution of noise constitutes a further complication. This type of noise is especially problematic at low signal-to-noise ratio (SNR) regions. LÄS MER
