asltk 1.0.0

A quick to use library to process images for MRI Arterial Spin Labeling imaging protocols.

Arterial Spin Labeling Toolkit (asltk)

Welcome to the ASL toolkit!

This library was designed to assist users in processing Arterial Spin Labeling (ASL) MRI images, from basic imaging protocols to the state-of-the-art models provided in the scientific literature.

The major objective of this project is to give an open-source alternative to researchers in the MRI field. A profound knowledge of computing and data modelling is not a prior demand. It is expected that a simple set of Python commands can be helpful in fast prototyping an ASL experiment or even collecting simple quantitative ASL-based information.

Please read the full documentation to get more details about the usage, implementation and updates in the asltk library.

Also, feel free to contribute directly to the project! Check it out the issues at the repository and get in touch to the developers of the project.

How to install

A quick to use install is via pip, as follows:

[!NOTE] The installation requires Python 3.9 or higher

pip install asltk
