Welcome to LQ.

A PACS (Picture Archiving and Communication System) network, storing .dcm imaging and supplying them over the DICOM (Digital Imaging and Communications in Medicine) network protocol, may be part of a HIS (Hospital Information System or CIS). HIS, CIS and RIS (Radiology Information Systems) are specialistic systems conforming to say HL7 (Health Level 7) protocols (see also ANSI: Standards Developing Organizations). So I don't get it. This specialist market is big enough for you to be able to use your favourite searchengine for terms like PACS, DICOM (dclunie.com), HIS, HL7 (Wikipedia), OHF (Eclipse.org), IHE (IHE.net) and find links yourself like:

* If you're an enthusiastic amateur I suggest you read up on DICOM and HL7 before dumping overly broad questions like that on sites hoping for an all-encompassing answer suited to your specific situation while providing nothing and no shown efforts yourself. If you're a professional looking for implementation I'd strongly entertain the idea of hiring professional medical consultants. This isn't one of those "wee projects" for a single rainy monsoon season. And I wouldn't run F10 either.

As unSpawn says, 'Redhat' Fedora 10 ( kind of beta ) is not recommended,

Suggest : 'Redhat' CentOS 5.2 ( has long time support ).
