Eric Tamm MD, PRESENTER: Nothing to Disclose

Abstract: HTML Advanced postprocessing techniques, such as Volume Rendering (VR), and multiplanar reformations (MPR) coupled with the thin section imaging available with multidetector CT (MDCT) offer new perspectives for abdominal imaging. Unfortunately, the traditional paradigm has been the review of axial images on PACS stations, and the construction of post processed images on advanced workstations which have typically been in a separate location. To eliminate this separation, several manufacturers are now offering to incorporate entire postprocessing workstation programs, usually with limitations, into PACS workstations. However, this approach demands significant hardware requirements, and typically a high cost to upgrade to this capability for every workstation. We present in this abstract our experience with a client-server model for distributing advanced postprocessing capabilities to a wide range of computers. The AquariusNET Server (TeraRecon , San Mateo, CA) utilizes hardware and software to perform advanced postprocessing in real time; users interact with the server via a thin client that can be downloaded using a web browser. Our instititution is currrently implementing the iSite (Stentor, Inc., Brisbane, CA) PACS solution for filmless reading for our Radiology Department. We have found that the AquariusNET thin client is capable of running simultaneously on the same computer platform as that running the Stentor PACS workstation without modification of hardware. It was possible from the Stentor PACS workstation to direct the Stentor PACS Archive to push images to the AquariusNET Server, to interactively direct the AquariusNET Server to create and view complex 3D VR images while using the PACS workstation, and to then push selected images to the Stentor Archive for distribution to our clinicians via the institution's self-developed Clinicstation application that incorporates Stentor for image viewing. We were also able to use the thin client on radiologists' office computers, and conference room computers with LCD projectors. Using this approach, it has been possible to routinely create complex postprocessed images on office computers for clinical, and academic purposes. Similarly it has been possible to perform real time complex postprocessing during case conferences to answer clinical questions (i.e., length of superior mesenteric vein involvement by pancreatic cancer), and to then transfer key images to the PACS archive for later retrieval by clinicians using Clinicstation.     To learn about the capabilities of using a thin client application for distributing advanced postprocessing capabilities for Multidetector CT data throughout the enterprise.(E.P.T. TeraRecon has loaned a workstation and the AQNET server for evaluation purposes to MD Anderson.)
