The birth of OsiriX

The OsiriX project started in November 2003 when Antoine Rosset MD, a radiologist from Geneva, Switzerland, received a grant from the Swiss National Fund to explore and learn about medical digital imaging. At first, the goal of the OsiriX project was to simply write a small software program to convert medical imaging DICOM files to a QuickTime movie file, in order to help a radiologist friend to create a teaching files database. But soon, Antoine Rosset realized it could do much more.

In June 2004 the first version of OsiriX was released on Antoine Rosset’s personal homepage. At that stage, it only offered a basic database and a simple medical images viewer, without post-processing functions or measurement tools. But that was enough to get noticed: an article about the OsiriX project was published in June 2004 in the Journal of Digital Imaging and became a reference. But Antoine Rosset came back to the Geneva University Hospital in Switzerland in October 2004 to continue his career as radiologist.

That’s when Joris Heuberger, a Math and Computer Sciences major from Geneva, joined the story in March 2005.

In June 2005, during Apple’s Worldwide Developer Conference (WWDC) in San Francisco, OsiriX team received two prestigious Apple Design Awards: Best Use of Open Source and Best Mac OS X Scientific Computing Solution It was already becoming the reference in medical images viewer that was going to inspire many others, athough never equal to the original.

In 2009, OsiriX became the official DICOM viewer for the Radiology Department of the Geneva University Hospital thanks to the support of Professor Ratib who had returned to Geneva a few years earlier as Chairman of the Nuclear Medicine service.


In March 2009, Antoine Rosset, Joris Heuberger and Osman Ratib created the OsiriX Foundation to promote informatics in medicine. This non-profit foundation offers grants to students for developing software in medicine and organizes awards to stimulate development in digital imaging and post-processing.

In February 2010, Antoine Rosset and Joris Heuberger created the company Pixmeo to create and distribute a certified version (CE, FDA, ANVISA) of OsiriX: OsiriX MD.


Today OsiriX has over 20 years of success with more than 1000‘000 users and has over 20’000 downloads per month. It is used in more than 190+ countries in 100k institutions.
