About Radiant
RadiAnt develops RadiAnt DICOM Viewer, a lightweight Windows application for viewing and analyzing medical images from CT, MRI, PET, ultrasound, and X‑ray. It sells commercial licenses (with a free trial) to radiology practices, hospitals, and researchers, and supports PACS query/retrieve, multi-modality workflows, and 2D/3D reconstructions. The software can open studies from local media and networked DICOM servers for clinical review and teaching use cases.
