Where LumaDICOM is better
- It is free, including MPR, 3D and the panorama.
- It exports 3D surfaces as OBJ/STL, which Ossidex does not.
Imports in detail
Both apps accept archives and some cloud links. Ossidex handles these sources:
| What you have | How it gets into Ossidex |
|---|---|
| Disc folder with DICOMDIR | Import the whole folder; the Windows viewer (.exe) next to it is skipped. If you pick the .exe by mistake, Ossidex suggests importing the folder instead. |
| ZIP / RAR / 7z / ISO | Imported as is, archives inside archives unpacked; password asked only for encrypted archives. |
| Cloud share link | Google Drive files and folders, Dropbox, OneDrive and SharePoint, iCloud Drive shared files, WeTransfer, Yandex Disk, Mail.ru Cloud, direct URLs. Interrupted downloads resume. |
| Loose .dcm files | Grouped into studies and series; files without UIDs or without the DICOM preamble are recovered where the data allows. |
| PACS | DICOMweb search (QIDO-RS) and download (WADO-RS). |
LumaDICOM lists ZIP, RAR, 7z and ISO archives and links from Google Drive, Dropbox and Yandex Disk.
Dental workflow compared
LumaDICOM reconstructs an OPG-style panorama from a CBCT. Ossidex’s arch is built for repeated clinical use: an automatic curve you edit point by point (move, insert, delete, extend), a panorama that updates live while you edit, numbered cross-sections along the curve with slice rulers, FDI or Universal tooth numbering, a HU probe with a bone-density guide, one arch per study that reopens where you left off, and a PDF report with the panorama and all cross-sections.
Who should pick which
- You want everything free and need STL/OBJ export: LumaDICOM.
- You connect to a PACS, open NIfTI or DICOMDIR discs, or need PDF reports: Ossidex.
- You work in a language other than English: Ossidex’s interface is available in 46 languages.
Both are free to install; the fastest way to decide is to open the same study in each.
Where Ossidex is different
- PACS connection through DICOMweb.
- NIfTI files, DICOMDIR discs and Enhanced multi-frame CT/MR.
- More link providers: OneDrive, iCloud Drive, WeTransfer and Mail.ru Cloud in addition to Drive, Dropbox and Yandex Disk.
- Measurements with a one-page PDF report and an arch report with all cross-sections.
- An editable arch: move, insert and delete points, with measurements carried over when you edit.
- 46 interface languages.
LumaDICOM is young and changing quickly; we compared against its public site and App Store listing and did not test every feature.
