From my experience with Horos, I found it excels at providing a powerful, free platform for viewing and analyzing medical images on MacOS. Its open source nature encourages customization and community-driven improvements, making it a valuable tool for radiologists and researchers. However, the Mac-only availability can be limiting for some users, and the interface may require a learning curve for beginners. Overall, if you need a robust DICOM viewer with advanced features like 3D reconstruction and PACS integration without licensing costs, Horos is a solid choice.
