RadiAnt DICOM Viewer is a popular medical imaging software used to view, analyze, and manage DICOM (Digital Imaging and Communications in Medicine) files. It's widely used by medical professionals, researchers, and students to visualize and interpret medical images from various modalities, such as X-rays, CT scans, MRI scans, and ultrasound.

The cost of Radiant DICOM Viewer varies depending on the version, licensing, and intended use. I recommend visiting the official website or contacting the vendor directly for more information on pricing and licensing options.
