The project was launched to fill a massive void left when OsiriX, a highly popular open-source viewer, transitioned into a commercially licensed, paid product (OsiriX MD). Sponsored by the Purview Foundation, Horos was built upon the original open-source codebase of OsiriX. It is fully compliant with DICOM standards and is distributed under the GNU Lesser General Public License (LGPL).

As an open-source project, Horos benefits from the contributions of developers worldwide. It is sponsored by Nimble Co LLC d/b/a Purview, but remains committed to its free, open-source roots. The community continues to provide feedback and suggestions, with "Release Candidate" versions made available for testing, helping to drive the software's evolution.

Horos is highly regarded for its ability to aid in pre-surgical planning. Surgeons and radiologists use it to create 3D reconstructions, allowing them to understand the spatial relationships between tumors and nearby, delicate anatomical structures. 2. Tumor Volume Analysis
Horos can act as a fully functional PACS node. You can configure it to query and retrieve image studies directly from your hospital or clinic’s central PACS server, send images to other workstations, or even act as a local mini-PACS server for a small practice. 5. Extendability via Plug-ins
Precise measurement is critical for diagnosis and treatment planning. Horos provides a complete suite of tools for drawing regions of interest and performing quantitative analysis. These include tools for linear measurements, angle measurement, area calculation (with statistics like min, max, and standard deviation), and text-based annotations. The allows for volumetric measurements, and advanced tools like calcium scoring and time-series analysis are available for more complex evaluations.
