DICOM viewer application for Mac OS X computers.

OsiriX is able to receive DICOM images (STORE SCP - Service Class Provider) from your PACS network. It is compatible with DICOM files and PACS networks.

OsiriX is a DICOM viewer application for Mac OS X computers

OsiriX has been specifically designed for image fusion, cardiac CT, multi-series MRI exams and 3D reconstructions. It supports 5D viewers for PET-CT series and Cardiac-CT exams.

Please read the 'Quick Manual' to learn how to do image fusion, use the 4D viewer and do 3D reconstructions. This alpha version is incomplete and doesn't include many features, but it will allow you to discover what is OsiriX. This first version has been developed in less than 4 months... Many, many new features will come! Please, send any comments, bug reports and ideas to improve OsiriX!
