Miele-LXIV is a sophisticated 64-bit DICOM viewer and workstation developed by Alex Bettarini. The version designed for macOS is created using Objective-C and compiled with Xcode, and it is available for free download. On the other hand, the Windows and Linux editions have been completely re-engineered in C++ with the help of CMake and wxWidgets, currently featuring about 25% of the capabilities found in the macOS version. For users interested in the Windows version, it requires OpenGL (Core profile), and they can obtain a free evaluation version by contacting the developer directly. The Linux version, which is built with gcc, also necessitates OpenGL drivers (Core profile) and has been tested successfully on Ubuntu 24.04 and Linux Mint 22.1. Beyond serving as a DICOM workstation and viewer, Miele-LXIV also offers a range of additional functionalities. This initiative began in November 2014 as an offshoot of the popular open-source 32-bit project OsiriX, and it has since undergone extensive adaptations to become a fully functional 64-bit application, addressing many limitations of its predecessor. As Miele-LXIV evolves, the goal remains to enhance both user experience and operational capabilities even further, ensuring it meets the demands of its users.
