I can’t provide a full unpublished paper, but I can point you to a solid, peer-reviewed academic reference on (the open-source medical image viewer, a free alternative to OsiriX).
In the medical imaging landscape, accessing and analyzing radiological data efficiently is critical for patient care, research, and education. For years, proprietary Picture Archiving and Communication Systems (PACS) dominated the market, often locked behind expensive licensing fees. Enter , a free, open-source medical image viewer that has become a staple for clinicians, researchers, and students worldwide.
2D viewer, 3D volume rendering, surface rendering, and curved planar reformation (CPR). Regulatory Status: While widely used in clinical research, Horos itself is not FDA approved horos software
Reports and studies can be coordinated and saved together as DICOM files for easy management. General Process
The Horos project has seen slower development since 2020, with the original lead developer stepping back. However, the community continues to maintain the source code. As of 2025, Horos remains stable and functional on the latest macOS versions (Sonoma and Sequoia).

Horos functions as a DICOM listener, allowing it to receive scans directly from imaging modalities (like an MRI machine) or local PACS servers. It can also query and retrieve studies from remote databases, making it a valuable node in a hospital network. Horos vs. OsiriX: Understanding the Connection
Before diving into the specifics of Horos, it's important to understand the environment it operates in. A DICOM viewer is a software application designed to open, view, and manipulate medical images in the DICOM format, which stands for . This standard is used worldwide to store, exchange, and transmit medical images and associated patient information, acting as a universal language that ensures compatibility across different imaging devices and systems from various manufacturers. It's the foundational technology that allows a CT scan, an MRI, or an ultrasound to be viewed, shared, and analyzed by different medical professionals, regardless of the equipment used to generate the images.
Horos organizes images by Patient Name, Study Date, and Modality. You can create local folders, burn studies to patient discs, or export images into standard formats like JPEG, PNG, or QuickTime movies for presentations. Regulatory Status: While widely used in clinical research,
provides the latest software versions and community-driven documentation. Source Code
The software itself is robust and accurate—the measurements are precise—but the lack of regulatory clearance is the only barrier.
