21. A study of susceptibility-weighted MRI including a comparison of two different implementations
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Susceptibility Weighted Imaging is an MRI- and post-processing technique that utilize the phase information from the MR signal to enhance the contrast in areas with different susceptibility than surrounding tissue in T2*-weighted images. This technique is becoming more and more important as a clinical tool. READ MORE

23. Dosimetric and geometric evaluation of MRI as the only imaging modality for the radiotherapy treatment process of localized prostate cancer
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Introduction MRI provides better soft tissue contrast than CT and is an invaluable tool in the radiotherapy treatment process. The gold standard today is image fusion of MRI and CT data where targets and organs-at-risk are delineated on the MRI data and the dose calculation is performed on the CT data. READ MORE

25. Denoising of Complex MRI Data by Wiener-like Filtering in the Wavelet Domain - Application to High b-value Diffusion Weighted Imaging
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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. READ MORE
