Saga DICOM Viewer
Saga DICOM Viewer is a free, browser-based DICOM viewer for opening .dcm files without installing software. Drag a file or a study folder into the page and the images render locally; nothing is uploaded and no account is needed. It runs on Mac, Windows, Chromebook and Linux in any current browser.
Built on the open-source OHIF v3 platform with a Saga shell. Alongside image review (scroll, window/level, pan/zoom and basic measurements), it includes a DICOM tag browser and tag editor with VR-aware validation and save-as, a conformance validator that checks loaded files against the NEMA PS3 standard and links each issue to its spec section, and a launcher for opening public studies from the OHIF demo dataset or NCI Imaging Data Commons, or connecting to a DICOMweb server.
For integration engineers, researchers, students and clinicians who need to open or check a DICOM file quickly. Not for diagnostic use. Made by Saga IT, a healthcare IT consulting and software firm.
