Loading studies

Doomina accepts the formats you typically get from a CD/USB or a PACS export.

Supported inputs

• Folder — a whole directory tree; subfolders are scanned recursively.
• .zip — a zipped study (extracted in the browser).
• DICOMDIR — the index file from CD/DVD exports.
• .dcm / .dicom and extension-less DICOM files.

How to open

1. Drag & drop onto the viewer, or use Open DICOM → Open Folder / Open .ZIP.
2. Files are grouped into studies and series by their DICOM tags.
3. The first series of a newly opened study displays automatically.

What happens to my files?

Everything is parsed and rendered locally in your browser. Files are never uploaded. Opened studies are cached in this browser (IndexedDB) so they reappear after a refresh, and — if you link a library folder — written to that real folder too. See Privacy & storage.

Troubleshooting

• Nothing loads — make sure the folder actually contains DICOM files (not just JPEG/PDF reports).
• Only some images show — large series stream in progressively; wait for the count to finish.
• A compressed transfer syntax — most common JPEG/JPEG-LS/JPEG2000 syntaxes are supported via the built-in codecs.
