Synthetic MRI Visualization Principles and Application
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
This work is aimed at developing and implementing visualization methods forquantitative MRI (i.e quantified T1, T2(*) and PD).Conventionally MRI images depend heavily on the MR camera settings, anda new scan is generally required for each different image. With quantitative MRIdata acquisition methods, however, virtually any MR contrast image can be postsynthesized.The method to synthesize and visualize MR contrast images is describedin this thesis.Furthermore entirely new visualization methods are developed. These can notbe acquired solely using some MR pulse sequence, post-processing is required. Twonew visualization methods are presented in this thesis: vector MRI and color MRI.In vector MRI the quantitative MRI parameters are viewed as a vector fieldand the vector norm constitutes the image pixel intensity.In color MRI the quantitative MRI parameters are viewed as color channelswhich combined generates a color image.Also, in this thesis, methods to quantify perceived image weight, i.e T1-weight,T2-weight and PD-weight, are developed as well as methods to optimize contrast for the different imaging modes.
