A Standards-based Solution for Fast and Efficient Streaming and Remote Viewing
of Medical Imagery
AccuRad Stream™ is an enterprise medical image distribution and viewing solution that enables standards-compliant image streaming between multiple data sources and viewing clients.
The AccuRad Stream Server incorporates JPIP streaming functionality with PACS. The AccuRad Stream Viewer connects with the JPIP enabled PACS to retrieve and stream images via JPIP.
The result is a standards-based solution that addresses the problems associated with viewing large amounts of medical image data over constrained networks.
In addition, it avoids problems related with the proprietary nature of many similar systems in use today, in part by converting images to JPEG 2000 format so they can be streamed to viewers using the DICOM JPIP protocol. |

AccuRad Stream includes several components
in addition to Stream Server and Stream Client:
1. AccuRad J2KSuite, the leading JPEG2000 Software Development Kit (SDK)
in the market today.
2. AccuRad JPIPStream, an SDK for building JPIP-based client/server solution
3. AccuRad DICOMView, a lightweight ActiveX control for streaming, viewing, and manipulation of medical images. DICOMView includes a scriptable API for rapid application development of viewing clients.
The AccuRad Stream Server
The AccuRad Stream Server is a middleware application server that receives and prepares medical image data for streaming to remote clinical and diagnostic locations. The Accurad Stream Server consists of a number of Acquisition Services and an Application Server.
- Acquisition Services are mechanisms for importing medical image data from one or more disparate PACS or image sources into the AccuRad Stream Server for processing. In the application server, data is compressed (if necessary) and a cache of images is built based on a variety of criteria related to criticality, access patterns, and aging.
- The Application Server builds an image manifest which includes information about the location of the images. Once the viewing client calls for a study, the manifest is retrieved by the viewer.
- A session is established via the manifest and then images are requested by the client via JPIP. The Application Server receives the request, locates the image and/or region of an image requested, determines if the image or region has already been delivered, and responds accordingly with JPIP image data or notifications.
AccuRad Stream Client
- AccuRad Stream Client is a reference application provided with AccuRad Stream to demonstrate a fully functional medical imaging client. The Stream Client is built around AccuRad DICOMView as a Web browser application. DICOMView may also be hosted in any client container that can make use of ActiveX.
- The application exposes many of the functions image reviewers rely on to perform their reads. Multiple image layouts are supported. Thumbnail navigation is also presented and studies are broken apart into their constituent series for multi-series review. Context-based predictive image loading is also included to optimize the reading experience as reviewers move through a stack of images. The Client and DICOMView are highly customizable and functionality can be accessed and abstracted via scripting methods.
- DICOMView functionality is also very robust and mature, exposing the tools radiologists need to manipulate and work with images. Window-level, zoom, pan, scroll, scoutlines, linking, annotations, overlays, measurements, and cine-loop controls are just some of the functions available.
