Introduction

The dcm4chee-wizard is a web-application that provides a graphical user interface for configuration of DICOM devices compliant to the DICOM Application Configuration Management Profile, specified in DICOM 2011, Part 15, Annex H.

In addition to the configuration of basic DICOM devices, the application has been extended to allow for the configuration of dcm4che specific DICOM implementations, such as the DICOM proxy (dcm4chee-proxy) and XDS.b applications (dcm4chee-xds, included in version 1.1.0).

Supported configuration backends include LDAP and Java Preferences.

Building

Prerequisites

Building the dcm4chee-wizard and dependencies requires Maven 3.

Before building dcm4chee-wizard, check out and build the following projects:

dcm4chee-wizard

> mvn install -P {standalone|proxy|jdbc|jdbc-proxy}

standalone: basic web-app with configuration options for supported devices
proxy: in addition to standalone includes dcm4chee-proxy web-application (bundle)
jdbc: in addition to standalone contains a deployment dependency for use with
dcm4che-jdbc-prefs, a wrapper for storage of Java Preferences data in a SQL backend.
jdbc-proxy: combination of proxy and jdbc profiles

JBoss Setup

Dependencies

To run dcm4chee-wizard within JBoss AS7 requires dcm4che-jboss-modules to be installed, which can be found in the dcm4che-3.x DICOM Toolkit (https://github.com/dcm4che/dcm4che).

Unpack dcm4che-jboss-modules-<version>.zip into the JBoss AS7 folder.

Container Configuration

Create a directory dcm4chee-wizard inside the container configuration directory (e.g. <jbossDir>/standalone/configuration/dcm4chee-wizard) and copy all files from dcm4chee-wizard/dcm4chee-wizard-war/src/main/etc/ into it.

Alternatively, specify the directory path with the 'dcm4chee-wizard.cfg.path' system property.
Strings specified with

${property.name}

will be evaluated accordingly.

If planned to use Java Preferences as configuration backend, delete the file ldap.properties from <jbossDir>/standalone/configuration/dcm4chee-wizard/.

If planned to use a LDAP configuration backend, edit the file <jbossDir>/standalone/configuration/dcm4chee-wizard/ldap.properties and set the connection and authentication parameters according to the LDAP server configuration.

Deployment

To run dcm4chee-wizard in a JBoss AS7 instance, deploy dcm4chee-wizard/dcm4chee-wizard-war/target/dcm4chee-wizard-war-<version>.war via the JBoss command line interface or by copying it into e.g. <jbossDir>/standalone/deployments/.

Example:

i) make sure the JBoss instance is running

ii) start the command line interface: <jbossDir>/bin/jboss-cli.sh -c

iii) call the deploy procedure: deploy <buildPath>/dcm4chee-wizard-war-<version>.war

Configuration of supported device service

For each device with network services supported by the wizard (currently dcm4chee-proxy and dcm4chee-xds), configure the following system property in the container configuration (e.g. <jbossDir>/standalone/configuration/standalone.xml):

<system-properties>
    <property name="org.dcm4chee.device.<device-name>" value="http://<device-url>"/>
</system-properties>

Example:

In case the wizard was compiled with the profile 'proxy', the bundled proxy application can be configured as followed:

<system-properties>
    <property name="org.dcm4chee.device.dcm4chee-proxy" value="http://${jboss.bind.address}:${jboss.bind.port}/dcm4chee-wizard/proxy-application"/>
</system-properties>

Configuration

Use the 'New Device' button to create a configuration for a network entity. Supported configuration types are described below.

Basic Device

A basic device can be used to describe network entities such as modalities or workstation. The available configuration options are based on the DICOM standard and include DICOM device parameters, network connection parameters, DICOM network application entity parameters including transfer capabilities supported by the AET, as well as HL7 application parameters.

Proxy Device

A proxy device extends the basic device with support for dcm4chee-proxy specific configuration options.

Additional Device Attributes

  • Scheduler Interval: interval to check for scheduled c-stores and logging
  • Forward Threads: maximum number of concurrent forward threads
  • Stale Timeout: Stale timeout of cached configuration in seconds 0 (=never invalidate cached configuration) if absent

Additional Device Sub-Nodes

  • Audit Loggers: create a local audit logger that will send messages to a configured audit record repository

Additional Network AE Attributes

  • Spool Directory: directory for temporary DICOM file
  • Accept Data On Failed Association: temporary store data on failed negotiation with Called AET
  • Enable Audit Log: enable audit logging
  • Delete Failed Data Without Retry Configuration: delete files based on error without retry configuration after first failed forwarding
  • Proxy PIX Consumer: Application^Facility name of local PIX Consumer Application
  • Remote PIX Manager: Application^Facility name of remote PIX Manager Application
  • Fallback Destination AET: send DICOM objects to target Called AET as fallback option

Additional Network AE Sub-Nodes
