Introduction

1.1 What is DEXcom?

DEXcom is the DICOM networking component of the DEXIS Software. It is an
add-on to the DEXIS Software implementing communication with DICOM
servers. The DEXcom component is therefore only needed by large enter­prises running a DICOM conformant hospital management system. The
DEXIS Software connecting to such a system and thus including the DEX­com component is called DEXIS Enterprise Edition.

The DEXcom component (or Application Entity in DICOM terms) implements
the following DICOM functionality:

• DEXcom can verify communication with a DICOM server; it is thus a Serv­ice Class User (SCU) of the Verification Service Class.

• DEXcom can store images on a DICOM server; it is thus a Service Class
User (SCU) of the Storage Service Class.

• DEXcom can query DICOM servers for patients, studies, series, and imag­es; it is thus a Service Class User (SCU) of the Query/Retrieve Service
Class.

• DEXcom can receive images from a DICOM server and store them in its lo­cal database; during this operation it serves thus as a Service Class Pro­vider (SCP) of the Storage Service Class.

• DEXcom can query Modality Worklist Servers for entries; it is thus a Serv­ice Class User (SCU) of the Modality Worklist Service Class.
