Diffusion sampling length ratio
WebFeb 25, 2024 · The diffusion MR images were imported in the DSI studio software, setting up the brain mask and using the generalized q-sampling imaging (GQI) reconstruction … WebIn DSI Studio, the GQI implementation uses 0.015 for 6D, and thus the diffusion length ratio appears longer. (e.g., a ratio 1.25 is in fact 1.145). The optimal value for "diffusion sampling length ratio" depends on the signal to noise ratio and the b-table, and it is … GQI has a length parameter (termed diffusion sampling lengh ratio) to specify … DSI Studio is able to export ODF data for further processing and visualization.
