CHILI - Teleradiology according to German x-ray ordinance

There is no doubt that the NEXUS / CHILI GmbH can be considered to be a pioneer of teleradiology in Germany. Precursors of the NEXUS / CHILI solution were operated routinely in hospitals as early as in the beginning of the 90s. Functions of teleradiology are deeply anchored in the software architecture.
Therefore, each CHILI PACS is also a teleradiology system and each teleradiology system a little PACS.
The specific teleradiology products differ by their functionality and the protocols used for data transmission. Depending on the scenarios of use, it is possible to choose the optimum solution for the task to be performed. We will advise you in detail.

Features

Partner-dependent transmission protocols (e.g. https, DICOM, DICOM E-Mail)
Compression with or without loss with automatic encryption
Rule-based forwarding depending on weekday, time, AET, port, DICOM header contents
Fault tolerance and automatic continuation after interruptions

Benefits

Can be integrated with any PACS and any DICOM modality
Time saving due to automated acceptance and consistency testing according to DIN 6868-159
Easy IT management as no VPN connections are used
Solution in compliance with legal requirements based on extensive counseling

Teleradiology Teleradiology Gateway Basic

The CHILI Teleradiology Gateway Basic is used for receiving and automatically forwarding DICOM image data. Arriving data undergo intermediate storage in a database. In the case of network interruptions, transfers that have failed are taken up again automatically. Therefore, receipt of all data by the addressee is guaranteed. Transfers can be monitored via a web-based administration interface.

By default, the product contains the protocols DICOM C-Store (SCP and SCU), as well as the transmission via http/s. The DICOM E-Mail protocol is an additional option.

Features

Protocols included: DICOM C-Store, http/s, DICOM E-Mail (optional)
DICOM receiver node: 3 C-Store SCP
Transmission nodes: unlimited number of C-Store SCU
Rules for automatic forwarding depending on various parameters (e.g. AET, port, day of week, time)

Benefits

Transmission on existing modality or in PACS
Sending data in the background without user interaction
Automatic forwarding to different partners
Largely maintenance-free

Teleradiology Teleradiology Router

The Teleradiology Router is a program that can be installed locally and receives data from up to three DICOM nodes as C-Store SCP and forwards them to a defined other CHILI system via https-based CHILI protocol using compression.

Moreover, the system actively queries data via https-based CHILI protocol from a defined CHILI system, buffers them and sends the data to a DICOM node in the local network in the form of C-Store SCU.

The DICOM header data can be modified with configurable values during transfer.

Features

Protocol: http/s
DICOM receiver node: 3 C-Store SCP
Forwarding to another existing CHILI system (e.g. PACS, web server, gateway)
Rules for automatic forwarding depending on various parameters (e.g. AET, port, day of week, time)
Configurable modification of DICOM header data (e.g. prefix before study ID)

Benefits

The cheapest variant of teleradiology when a CHILI partner is available
Sending data in the background without user interaction
Automatic forwarding
Largely maintenance-free

Teleradiology Teleradiology Gateway Advanced

The CHILI Teleradiology Gateway Advanced is used for receiving and saving DICOM image data. The image data can be sent via the web-based CHILI Viewer or automatically transmitted to the teleradiological partner according to defined rules.

In the case of network interruptions, transfers that have failed are taken up again automatically, so that it is guaranteed that all image data reach the addressee.

The product involves a web-based viewer for visualization that has interpretation quality. Transfers can be monitored via a web-based administration interface.

By default, the product contains the protocols DICOM C-Store (SCP and SCU), as well as the transmission via http/s. The DICOM E-Mail protocol is an additional option.

Features

Web-based viewer for display and interpretation of data sent and received (two simultaneous users)
Protocols included: DICOM C-Store, http/s, DICOM E-Mail (optional)
DICOM receiver node: 3 C-Store SCP
Transmission nodes: unlimited number of C-Store SCU
Rules for automatic forwarding depending on various parameters (e.g. AET, port, day of week, time)

Benefits

Viewer that is suited for interpretations (EU medical device class IIb)
Transmission on existing modality or in PACS
Sending data in the background without user interaction
Automatic forwarding to different partners
Largely maintenance-free

Teleradiology Teleradiology by web distribution

CHILI Web's high quality of software is not only used for in-house image distribution, but also for teleradiology. Various scenarios of use can be thought of:

Within the scope of teleradiology according to the German X-ray ordinance, the teleradiologist can access images at home and interpret them using the CHILI Web Viewer.

Pictures may be provided to referring physicians or patients (temporarily). It is possible to save the data (download) on the own computer and to upload previous studies.

Referring physicians or patients can upload previous studies prior to treatment or admission to hospital.

Features

No software installation on the Clients, since web-based
No dependence on specific browsers or versions
Can be combined with PACS systems of other manufacturers
Compression: with or without loss (with or without loss of the diagnostic meaningfulness)
Action taken in view of data protection and data safety: Encryption per https, client certificates, web application firewall

Benefits

No software installation for the user. Only an internet browser (any one) is required
Integrated functions for acceptance and consistency testing of teleradiology according to the German x-ray ordinance (DIN 6868-159) included
Cost optimization by teleradiology at night and on weekends
Process improvement by uploading previous studies prior to admission to hospital
Improved reputation among referring physicians and patients by providing results of previous studies
Increase of referrals
