Horos is a free, open-source medical image viewer intended for use by radiologists, clinicians, and researchers. It is built on OsiriX (another famous DICOM viewer) but is completely free and community-driven.
Similar to OsiriX, Horos supports a vast array of plugins to expand its functionality, such as image segmentation or perfusion modeling. Primary Applications in Healthcare

Employed in pediatric high-grade glioma cases for postoperative analysis, specifically measuring the extent of resection. horos software
Horos is not just a "picture viewer." It is a robust DICOM workstation that rivals software costing thousands of dollars. Here are its headline features:
This is a cornerstone feature of Horos. Using its VTK integration, it provides high-performance 3D volume rendering, allowing users to visualize anatomical structures in stunning detail. The tool is particularly valuable, offering synchronized orthogonal and curved planar views that are essential for precisely planning surgical approaches and analyzing complex anatomies.
: Many "deep learning" papers use Horos as the "ground truth" tool where expert radiologists manually annotate images to train neural networks. Parameter Mapping : Specialized studies, such as those from Stanford University Horos is a free, open-source medical image viewer
Horos software packs a significant punch, offering a suite of features that rival even some commercial DICOM viewers.
Unlike many medical imaging applications that are designed for Windows, Horos is specifically optimized for macOS, providing a native, smooth user experience on Apple devices.
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 including: Highlights structures with higher attenuation
The use of Horos software offers several advantages, including:
Highlights structures with higher attenuation, useful for CT angiography.
