Check your Covid19 CT scan using Miele-LXIV, free and OpenSource.


I would like to announce the Miele-LXIV project, a 100% DICOM standard compliant image viewer for macOS.

macOS App store download

You can also install the build binary directly from the macApp Store:

Build from source in 5 easy steps

If you want build the project with all its dependencies yourself then start here:


The software is 100% free, the License is GPLv3.0.
