AirQuant

AirQuant is an open source framework for analysing macro tubular networks in medical images such as airways.

Given centreline of the tube anatomy it can interpret the structure, extracting measurements. By also providing the original image it can derive detailed measurements diameter measurements. Facilitating detailed quantitative clinical analysis.

Please see the https://airquant.readthedocs.io/ regarding information on installation, use and tutorials. See https://github.com/ashkanpakzad/AirQuant for GitHub repository.

Open to ★★★★★, issues, discussions and contributions!

Would really appreciate a message or a star if this has been useful for you!
