Brain MRI Viewer

MRI viewer and windowing tool.

The motivation behind this project was to implement MRI preprocessing, visualization and windowing from scratch.

With this code you can:

• Visualize the slices of each view (sagittal, coronal and axial) of your MRI NIfTi file (3 or 4 dimensions)
• Apply windowing to the MRI by managing the window width and level

---

Project setup

You can clone the repository by using the command:

    $ git clone https://github.com/enriquemondragon/Brain_MRI_Viewer.git

Then, in the project's folder, you can execute the Makefile to setup the project and activate the created environment:

    $ make
    $ source venv/bin/activate

---

Usage

By default when loading an MRI, you will be able to visualize all three views at the same time

    python3 brain_mri_viewer.py --input [NifTi_file]

If you want to see only 1 view at a time, yo can specify it with the view flag

    python3 brain_mri_viewer.py --input [NifTi_file] --view {sag, cor, axi}

For applying windowing you can use the window flag in either cases

    python3 brain_mri_viewer.py --input [NifTi_file] --window
