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 yze 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
