The Utility and Impact of Horos: An Open-Source DICOM Viewer for Medical Research and Clinical Planning

Horos is a free, open-source medical imaging software for macOS, derived from the OsiriX project. It provides a full suite of post-processing capabilities for

(Digital Imaging and Communications in Medicine) datasets, including 3D volume rendering and multiplanar reconstruction (MPR). This paper examines the technical capabilities of Horos, its integration into surgical workflows, and its role as an accessible alternative to proprietary imaging platforms. 1. Technical Overview and Development Horos was developed on the OsiriX 5.8

platform after OsiriX transitioned to a proprietary model. Licensed under the GNU Lesser General Public License (LGPL-3.0), Horos maintains the 64-bit performance necessary for handling large clinical datasets without the image-count limitations found in free "Lite" versions of commercial competitors. Exclusively for Core Functions:

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

for diagnostic use; it is often utilized for education and preoperative planning where approved commercial systems are unavailable. 2. Clinical and Research Applications

Horos serves as a critical bridge between raw medical imaging and advanced clinical interventions.

Here’s a concise guide to getting started with Horos, a free, open-source medical image viewer for macOS (based on OsiriX).
