Creating plugins in Python

April 1st, 2020

As part of our efforts to support the fight against the coronavirus pandemic, we today announce the release of the first version of the Python plugin for Orthanc! This plugin can be of great help to anyone wishing to automate her imaging workflow, to design/train new machine learning algorithms, or to deploy AI systems directly in clinical setups. Given the huge need for medical imaging in order to cope with COVID-19, we hope this contribution will prove to be helpful.

July 17th, 2018

Today, we are excited to announce that the Orthanc project officially supports the highly popular MySQL and MariaDB databases through dedicated, free and open-source plugins!
