You can use OsiriX as a PACS server with these benefits:
- Based on OsiriX DICOM engine and Database (SQLite) engine
- Unlimited number of simultaneous clients
- Manage your PACS through OsiriX GUI
- Fully compatible with Mac hardware and software
- Fully compatible with DICOM protocol (C-Move, C-Store, C-Find, C-Get, WADO)
- Seamless integration with any DICOM viewers, through the DICOM protocol
- Web access through built-in web server, built-in Java viewer compatible with any OS
- Expansion: write your own plugins to extend the integration with any protocols/systems, including EMR, RIS or HIS.
Typically a PACS network consists of a central PACS server which stores a database containing the images, and of multiple clients that can retrieve and display these images on medical imaging software. The images are stored in DICOM format. The modalities (MRI, CT, PET, Ultrasounds, …) send the images to the PACS Server by using a DICOM “push” (DICOM C-Store). The server and the clients communicates by using the DICOM protocol (DICOM C-Store, WADO or Query & Retrieve). The clients display the images by using a medical imaging software: a DICOM viewer.
Each computer in a DICOM network are identified by their network address (IP address), a communication port (TCP/IP port) and a name (AETitle): each computer is a DICOM Node in the DICOM network. IP address, TCP/IP port number and AETitle is the information required to connect each DICOM Node to the DICOM network. These informations can be found in the Preferences > Listener window in OsiriX.
Hence, to build a PACS, you need:
- A PACS Server: a computer with a lot of hard disk space and a PACS Server software. The PACS Server software needs to be robust, working flawlessly 24/7, with a powerful database engine, capable of storing millions of DICOM images.
- PACS Clients: computers with a DICOM viewer software, like OsiriX. These PACS Clients can query and retrieve the DICOM images from the PACS server, by using the DICOM network protocol (DICOM C-Move, C-Store, C-Get, C-Find, WADO, …).
The important qualities of a DICOM viewer are:
- Fast transferring time (only limited by the network bandwidth)
- Fast loading time to be able to load and browse 1’000 images in less than few seconds
- Complete DICOM protocol supports to handle all different types of DICOM images
- Powerfull 2D imaging functions to analyze the images (ROIs, window levels, zooming, ….)
- 3D post-processing functions to view the datasets in volume rendering, MPR or MIP
- Image fusion support to multi-modal modalities like PET-CT, PET-MR, SPECT-CT studies
