DEXIS® DICOM Conformance Statement 3.0

1Introduction

This chapter provides general information about the purpose, scope and contents of this Conformance Statement.

1.1 Scope and Field of Application

The scope of this DICOM Conformance Statement is to facilitate data exchange with the DEXIS specifies the compliance to the DICOM 3.0 standard. It contains a short de scription of the applications involved and provides technical information about the data exchange capabilities of the equipment. The main elements de scribing these capabilities are: the supported DICOM Service Object Pair (SOP) Classes, Roles, Information Object Definitions (IOD) and Transfer Syntaxes.

The field of application is the integration of the DEXIS equipment into an environment of other medical devices and practice management software. This Conformance Statement should be read in conjunction with the DICOM 3.0 standard and it’s addenda.

1.2 Intended Audience

X-ray system and the DEXIS Software suite. This document

This Conformance Statement is intended for:

• system integrators of medical equipment,

• software designers implementing DICOM interfaces.

It is assumed that the reader is familiar with the DICOM 3.0 standard.

Readers wishing to obtain more familiarity with the content and terminology of DICOM 3.0 standard are encouraged to obtain and review the standard prior to reading this Conformance Statement. More information on acquiring this doc ument and its updates on the DICOM standard may be found on the website of the National Electrical Manufacturer's Association (NEMA) at http://www.ne ma.org.

1.8 Connectivity and Interoperability

This Conformance Statement by itself does not guarantee successful interoperability of DEXIS equipment with non-DEXIS equipment or non-DEXIS software. The user (or the user’s agent) should be aware of the following issues: The implementation of the DEXIS DICOM interface has been carefully tested to assure correspondence with this Conformance Statement. But the Conform ance Statement by itself and the DICOM standard does not guarantee interoperability of DEXIS modalities and modalities of other vendors. The user (or the user’s agent) must compare the relevant Conformance Statements and if a suc cessful interconnection should be possible, the user is responsible to specify an appropriate test suite and to validate the interoperability, which is required. A network environment may need additional functions out of the scope of DI COM.

2Implementation Model

The DEXIS Software Release 6 is a comprehensive range of software modules that allow for tailored solutions in the dental imaging field. The software appli cations are categorized in packages, for instance the DEXwrite package for referral letters. The Application Entities responsable for exchanging data through the DICOM interface are:

DEXIS® DICOM Conformance Statement 3.0

• The DEXIS Import/Export Application Entity is integrated into the DEXray and DEXimage packages. It deals with the exchange of images through removable media.

• The DEXcom Application Entity is integrated into the DEXIS Administration package. It deals with the exchange of images through computer networks using the DICOM standard.

Through these two Application Entities the DEXIS Software provides the following DICOM data exchange features:

• DEXIS can export DICOM File Sets to removable media; it thus serves as DI-

COM File Set Creator (FSC). If the images are not internally stored in DICOM file format, they are converted when exported.

• DEXIS can browse through DICOM File Sets on removable media and can im-

port images from these file sets; it thus serves as DICOM File Set Reader (FSR).

• DEXIS can verify communication with a DICOM server; it is thus a Service

Class User (SCU) of the Verification Service Class.

• DEXIS can store images on a DICOM server; it is thus a Service Class User

(SCU) of the Storage Service Class.

• DEXIS can query DICOM servers for patients, studies, series, and images; it

is thus a Service Class User (SCU) of the Query/Retrieve Service Class.

• DEXIS can receive images from a DICOM server and store them in its local da-

tabase; during this operation it serves thus as a Service Class Provider (SCP) of the Storage Service Class.

• DEXIS can query Modality Worklist Servers for entries; it is thus a Service

Class User (SCU) of the Modality Worklist Service Class.
