Thanks to PAXPort, we can receive large studies from
anywhere in the world within minutes, enabling cross-
border emergency services between different time-
zones.

PAXPort is an advanced DICOM Router, designed to enable
secure and high-speed transfer of imaging data between
disparate PACS over a Wide Area Network

network. Below you can see an example implementation diagram to inter-
connect various locations such as a diagnostic center and off-site radiologists,
data-center, tele-radiology provider, mobile units, etc.
