Miele-LXIV is a 64-bit DICOM viewer and workstation created by Alex Bettarini. The macOS variant, developed in Objective-C and compiled with Xcode, is offered as a free download. In contrast, the Windows and Linux versions are entirely re-engineered in C++ using CMake and wxWidgets, currently boasting around 25% of the features available in the macOS edition. To utilize the Windows version, OpenGL (Core profile) is required, and interested users can obtain a complimentary evaluation version by reaching out to the developer. Similarly, the Linux release, developed with gcc, also demands OpenGL drivers (Core profile) and has been verified for functionality on Ubuntu 24.04 and Linux Mint 22.1. Miele-LXIV serves not only as a DICOM workstation and viewer but also encompasses additional capabilities. This project originated in November 2014 as a derivative of the well-known open-source 32-bit project OsiriX, yet it has undergone significant modifications to transform it into a 64-bit application while eliminating many of the constraints imposed by the 32-bit predecessor. As a result, it continues to evolve, aiming to enhance the user experience and functionality further.
