In this work, we describe the public release of a software toolbox having the following design objectives: accomplish the pre-processing tasks of file input, image registration, denoising, and diffusion-tensor
Extracting the weighted means of individual fiber pathways can be useful when you want to quantify the microstructure of an entire white matter structure. This is specifically useful for tract based analyses, where you run statistics on specific pathways, and not the wholeRead More ByDo Tromp A ...
Further data processing was performed in Matlab (R2021b, The MathWorks, Natick, CA). The data from all DTI scans were denoised using a Marchenko-Pastur Principal Component Analysis (MP-PCA) algorithm22. The data were register over all b-values with elastix23 using an affine transformation to...
DTI standard (uncorrected for FW) and FW-corrected maps were calculated using an in-house MATLAB script26, which is available upon request. The FW maps were computed by fitting the following model at each voxel18: $${A}_{g}\left(D,f\right)=f\cdot (exp\left[-b{g}^{T}Dg \right]...
Image registration based distortion correction methods [1,2] attempt to correct the distortions by finding the B0 field as a symmetrical displacement field that will result in identical corrected images from blip-up and blip-down data sets. In areas of low SNR such as the region around the ...

Furthermore, linear regression as a function of treatment time regarding mean ADC values as well as volumes of GTV-P, GVT-N and HRS was fitted for all risk groups with Matlab. Additionally, relative changes of ADC and volume from baseline to every week of RT were evaluated for every risk...
This GitHub repository mainly contains MATLAB software for analysis of MD-dMRI data, and also some auxiliary routines for setup of acquisition protocols, motion correction, and image visualization.Three families of methods are currently implemented within the framework of MD-dMRI:...
Image processing Voxel-wise DTI and DBSI analyses were performed by an in-house software developed using MATLAB® (MathWorks; Natick, MA). The computation time for DTI and DBSI for each specimen is about 40 min. Co-registration between histology images and ex vivo MRI The two dimensional ...
Image analysis Image analyses were performed using a combination of image processing tools, including FSL (https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/)61, ANTs (http://stnava.github.io/ANTs/)62, and MATLAB (version 2021b). All MR images underwent thorough inspection for artifacts, including ...
