Flat Panel Digital Radiography Systems Designed to Replace Film Cassettes

Another new flat-panel X-ray image detector, at 17 x 17 inches, it is designed for permanent mounting in radiographic tables or wall stands, or for any application that requires a large field of view.

Varian Medical Systems, Inc. (Palo Alto, CA, USA), a key supplier of X-ray tubes and the PaxScan line of digital X-ray image detectors, presented these two new PaxScan systems at the annual meeting of the Radiological Society of North America (RSNA) in Chicago, IL, USA, from November 25-30, 2007.

Except for their physical size, both panels incorporate identical detector arrays and readout electronics, making them excellent radiographic imaging systems for any general-purpose room. Image data and control signals, which are based upon an industry standard Gigabit Ethernet interface, can be passed to and from these detectors using standard network interface cards. Images are transmitted instantaneously to the image processor for display and diagnosis. Housings and cable attachments are designed for simple integration into any diagnostic imaging system.

Both of these panels come bundled with VIVA software, a system design and development application for image acquisition and viewing on a workstation running Microsoft Windows. This software package provides an easy way for the original equipment manufacturer or system integrator to begin image analysis and system design quickly. Also included with VIVA is a complete Dynamic Link Library (DLL) to facilitate simple software development. Sample code is provided to ease the design of detector set-up and calibration, image acquisition, and image optimization. All Varian X-ray products come with excellent applications support to help customers with system design and development.
