QMRITools: processing and visualization tools for quantitative MRI data

Wow! That's a very advanced package! thanks for sharing! What kind of algorithm do you use for Phase Unwrapping? I just added this function to the WFR: https://resources.wolframcloud.com/FunctionRepository/resources/PhaseUnwrap

Which is for 1D, but can also be used for 2D (see examples). Is there a better approach in 2D or 3D?

The phase unwrapping i use works in 2D and 3D and is based on:
1. Abdul-Rahman HS, Gdeisat MA, Burton DR, Lalor MJ, Lilley F, Moore CJ: Fast and robust three-dimensional best path phase unwrapping algorithm. Appl Opt 2007; 46:6623. 2. Herráez MA, Burton DR, Lalor MJ, Gdeisat MA: Fast two-dimensional phase-unwrapping algorithm based on sorting by reliability following a noncontinuous path. Appl Opt 2002; 41:7437.

This method has worked nicely for me over the last few years.

I was working on a Fourier based method but was not happy with the results but in theory it should be much faster.

This seems to be absolutely awesome! I wish this (and an advanced version of MM) had been available fifteen years ago when I was still working in MRI! Many thanks for sharing - maybe I can play around a bit somewhen ...

Just another reminder to post your packages on http://packagedata.net/ :-)

At one time I used the Neurotica package a little bit, in particular for importing NifTI files. https://github.com/noahbenson/Neurotica There some overlap in functionality, so you may be interested in Neurotica.

I looked back at my very very old code, the first lines of code of the toolbox were written 12 years ago in Mathematica 6.0. The demos should give you some examples to play around with.

Congratulations on the excellent MRI Toolbox! Is there an option to process a standard mDixon sequence from a Philips 1.5 T scanner with the Ideal reconstruction?

Thanks,

Andre

In theory yes, I use data form a 3T Philips system in my research. You just need to export the complex data form the scanner which is needed for the iDEAL reconstruction.

Best Martijn
