RadiAnt DICOM Viewer is a Windows-based desktop application for viewing, processing, and exporting medical images stored in the DICOM format. It is designed to work as a PACS client and standalone DICOM viewer, supporting a wide range of imaging modalities including CT, MRI, PET, and angiography. The software enables radiologists, physicians, researchers, and medical professionals to open local DICOM files, retrieve studies from PACS servers, and analyze imaging data using 2D and 3D visualization tools. It supports multi-planar reconstruction (MPR), 3D volume rendering (VR), PET-CT fusion, and additional diagnostic measurement functions. RadiAnt is available for Windows systems and includes both 32-bit and 64-bit versions. It is designed to operate efficiently on modern multi-core systems as well as lower-resource machines. The application can also be deployed as a portable CD/DVD/USB viewer that runs without installation.
