PyQMRI - Model-Based Parameter Quantification
=============================================
PyQMRI is a Python based toolbox for quantitative Magnetic Resonance Imaging (MRI). Utilizing _PyOpenCL and a double-buffering scheme, 
it enables the accelerated reconsruction and fitting of arbitrary large datasets on memory limited GPUs.
Currently, PyQMRI supports the processing of 3D Cartesian and non-Cartesian (stack-of-) data.

Examples include T1 quantification from variable flip angle or 
inversion-recovery Look-Locker data, T2 quantification using a 
mono-exponential fit, or Diffusion Tensor quantification. 

In addition, a Genereal Model exists that can be invoced 
using a text file containing the analytical signal equation.

For a real world usage example have a look at the `Quickstart Guide`_.
The example can also be run interactively using |Colab|.

Installation and usage guides, as well as API documentaiton, can be found in the Documentation_


Sample Data
-----------
In-vivo datasets used in the original publication (doi: `[10.1002/mrm.27502]`_) can be found at zenodo_. If you use the sample data with the recent release of PyQMRI please delete the "Coils"
entry in the .h5 to force a recomputation of the receive coil sensitivities as the orientation does not match the data.


Contributing
------------
Development and code contributions should be done at our GitLab_ site to facilitate the CI integration and GPU availability there.
If you want to contribute please make sure that all tests pass and adhere to our `Code of Conduct`_. 
Prior to running the tests it is necessary to start an ipcluster. 
An exemplary workflow would be:
:bash:`ipcluster start &`
followed by typing
:bash:`pytest test`
in the PyQMRI root folder. It is advised to run unit and integration tests after each other as OUT_OF_MEMORY exceptions can occur if both are in one session, e.g.:
:bash:`pytest test/unittests`
:bash:`pytest test/integrationtests`

For more detailed instructions on how to contribute have a look at contributing_.


Limitations and known Issues:
------------------------------
Currently runs only on GPUs due to having only basic CPU support for the clfft_.
