AquariusNET Server 

The AquariusNET server is a uniquely powerful 3D enterprise server/ thin-client solution that maximizes the utility of MDCT, MR, and other medical imaging data throughout an enterprise. This central 3D processing server delivers real-time interactive 3D imaging to networked PCs running the AquariusNET thin-client application. Because there are no license fees for the deployment of the thin-client application and it runs on any PC open desktop, it can be applied to PACS diagnostic review stations HIS, RIS, and other informatic systems without the need for complex hardware upgrades or the need to move large 3D datasets across existing networks. All clinical applications, full functionality, and all 3D tools are available on all server models.

Thin-slice CTA and MRA datasets are processed on the central server with the results screened to standard networked PCs all DICOM data remains on the server and only the results are streamed "on-demand" as needed. Any standard networked PC can be used to navigate the thin-sliced DICOM datasets. This elegant server-side architecture allows for 3D anywhere on as many thin-client PCs as required since the servers' processing power can be scaled to accommodate multiple concurrent usage.

After the DICOM slices are sent to the AquariusNET server any physician can log onto the central server for interactive review from anywhere in the enterprise. Physicians interact in real-time with large slice studies from any remote PC location by streaming back incoming mouse commands. All clinical applications and diagnostic 3D tools are available including MIP, MPR, CPR, and 3D VR viewed in any oblique plane. Multi-modalities can be reviewed including CT, MR, PET, nuclear, ultrasound, X-A, CR, and DR. Multiple client systems can connect to the server and conduct interactive sessions concurrently. A license for unlimited use is included, so any PC can operate as a client on the network. Concurrent user sessions are restricted only by the limit of available server resources.

The AquariusNET system is designed to work over Intranet LAN networks and is also frequently used over wide area networks (WAN) which support suitable available bandwidth and low latency. In areas with limited bandwidth or high latency, TeraRecon's broad technology portfolio and iNtuition platform architecture can be designed to work around these limitations and still provide a highly optimized workflow.

AquariusNET offers uncompromised performance, image quality, and clinical functionality. It stands apart from other products because it employs a centrally shared server/thin-client approach. Low cost PCs, sourced by the hospital, are empowered by the AquariusNET server to deliver interactive 3D anywhere. In a "thick-client" system all of the DICOM slices are sent over the existing hospital network to each remote point of review which takes considerable time to transfer large files and can slow down other data traffic.

EliteAccess

EliteAccess, which is used to combine the AquariusNET thin-client with the advanced Aquarius Workstation, greatly increases radiology reading efficiency and enhances reading workflow. EliteAccess provides access to both streamlined workflow-optimized tools and high-end workstation applications through the convenience of the single AquariusNET thin-client user interface. The AquariusNET launches advanced 3D applications wherever they are required. A workstation-class computer is needed to post-process advanced workstation applications.

Image and Network Management

Integration with PACS: AquariusNET is integrated with most PACS systems enabling real-time 3D, MIP, and MPR tools to be launched directly from the patient worklist on the third color monitor of the PACS with a single button that launches all AquariusNET thin-client applications. By selecting 3D from the PACS toolbar or menu, the desired series will be loaded on the color monitor. All 3D reconstructions are processed using the AquariusNET thin-client server, not the PACS server.

Concurrent User Sessions: A standard AquariusNET server can manage over 10 concurrent thin-client interactive PC sessions simultaneously. Additional concurrent user sessions can be managed by adding VolumePro boards to the server and more powerful servers on the network.

Network Management: CT/MR datasets need only be routed to one location, unburdening the network from the task of transporting multi-gigabyte studies to various PACS or 3D workstations throughout the enterprise. Enterprise workflow tools include support for Single Sign On (SSO), which allows central administration of passwords to avoid the need to maintain password lists on multiple systems.

Patient Information Reconciliation (PIR): The AquariusNET will respond to messages from an institution's Radiology Information System (RIS) containing updates to header information for studies already present on the server. An example of when this feature is important is the case of trauma patient as scanned as "John Doe," whose images are distributed to many imaging systems including AquariusNET. Subsequently, when the patient's true identity has been established and enter into the RIS, all of the imaging systems holding the "John Doe" images need to update the header information of the files to reflect the true patient name. To this end, the RIS broadcasts a message using the HL7 protocol, to which AquariusNET now responds automatically.

Minimal Bandwidth Required: The AquariusNET server can be accessed outside the hospital using VPN over broad-band Internet or a WAN connection. Multi-modality review can be done over the Internet using DSL or cable modem since streaming data only requires small amounts of bandwidth. A single user session typically requires 2-3 Mbits per second with some amount of lossy compression activated. As long as there is sufficient bandwidth between the thin-client PC and the central server, remote review can be achieved across town, across the country, or across the world.

Scalable Processing: AquariusNET server can be upgraded with up to 16GB of volume memory (4 VolumePro boards can be populated per server); enough to manage 28,000 CT slices simultaneously from one centrally shared resource.

DICOM Query/Retrieve: Different modalities can push image studies to the server, or the server can query/retrieve studies from multiple modalities. The AquariusNET server can be implemented as a stand-alone system for multi-modality review. It can receive, send, or query data from any networked DICOM device to deliver real-time interactive 3D wherever or whenever post-processing is needed. It has the ability to query/retrieve asynchronously from the patient list, and the ability to enter a new series description from derived and capture images.

Long-Term Storage: TeraRecon offers redundant long-term archiving and management of images. The AquariusNET server is sold with internal RAID for storing the DICOM slices for some period of time, and additional external RAID storage can be added as an option.

Distributed Clustering Solutions for the Enterprise: The AquariusNET server can be clustered as a virtual networked resource, linking multiple servers with the network for integrated diagnosis and reading from any user on the network.

Integrated Reporting: Saving studies on the server within a Microsoft Word document automatically generates an interactive report. If two physicians are both connected to the server, one can open a small window in the other physician's PC and interactively manipulate data for remote consulting.

Security and Privacy: Outside the hospital's firewall, Virtual Private Network (VPN) access with user name and password authenticates the user access to the server.

AquariusNET Server Version 1.7

To activate 3D functionality, users download a small thin-client application from the server to any number of PC systems, located anywhere from physician reading rooms to surgical suites. TeraRecon recently announced the release of updated AquariusNET software with an emphasis on enterprise workflow and diagnostic tools. The AquariusNET server version 1.7 offers several new clinical workflow and cardiovascular analysis enhancements.

Clinical Applications, Editing, and Visualization Tools

Advanced Vessel and Soft Plaque Analysis: Automatic centerline extraction and editing with stenosis calculations. Soft Plaque histogram, color overlay, and volume calculation.

Scenes: For time-consuming post-processing tasks and more advanced 3D analysis, CT, and MR scans can be processed on the Aquarius Workstation for initial or complete post-processing. Once the post-processing is completed on the workstation, a file describing the work preformed (called a "scene") can be transferred to the AquariusNET server so that physicians may open the exam and pick up where the previous clinician left off.

Multi-monitor support with review of single modality or multi-modality images

Perspective rendering using the thin-client software

Multi-phase support is provided for time-dependent 3D MRAs and CTAs with the ability to link and synchronize the three viewing planes.

EliteAccess workflow technology, which allows access to high-end workstation applications already installed on the client PC through the convenience of the AquariusNET user interface.

Image Fusion: Multi-modality overlay with manual registration is offered for modalities such as CT and PET with advanced fusion mode with slab and cut-planes.

Automated Templates: Cases are loaded directly to the clinically appropriate 3D view. Preset templates can be created and saved using interactive rendering controls for easy viewing. Online processing engines automatically remove the CT table and rib cage, or calculate registration information if desired.

Cubic Viewing: Cube view is a quick examination tool to visualize volumetric regions-of-interest from inside or outside. This tool allows one to segment and view the pathology quickly for rapid assessment.

Movie Creation: The movie export tool provides for fast AVI creation from 2D and 3D images.

MPR Tools: Double-oblique MPRs can be viewed with 3D measurements on the oblique planes.

CPR Tools: Curved Planar Reformat allows curved or tortuous vessels to be visually stretched flat. Measurement tools are provided for stenosis review, distance, angle, and volume area.

CR Review: Side-by-side CR review is provided for AP, lateral, or oblique scans.
