Compare DICOM viewers: Ossidex vs desktop and mobile alternatives
Choose a viewer for the device and workflow you use. Ossidex brings studies to iPhone and iPad; the comparisons below also explain when a desktop or browser viewer fits better.
How to choose
- You read studies at a Windows or Mac workstation all day: a desktop viewer such as RadiAnt, MicroDicom, Weasis, Horos or OsiriX MD is the natural tool. Ossidex does not replace a reading workstation.
- You need to open a study away from the desk — in the consultation room, on a ward round, at home, or when a patient hands you a disc — a native iPhone/iPad app is faster than carrying a laptop. That is what Ossidex is built for.
- You work with dental CBCT: look for a panoramic arch with cross-sections. Ossidex has one; most general viewers do not list it.
