Display technology is getting more and more dynamic as vendors offer increasingly powerful displays, along with more sophisticated ways to mount and move them around. Use one large monitor to view multiple images, or put two displays side by side, or even add a third display, or perhaps project on a wall at high quality -- which are all possible with new controller boards. In short, display companies have geared up to match the ever-expanding capabilities of advanced visualization.
   
High bright technology is improving display quality and should also lengthen the lifespan of the newer displays with sharper, clearer images for longer. That's more bang for your imaging buck, which is good as the really cool monitors and peripherals you can read about below aren't free. 
   
Along those lines, further good news at RSNA came in the form of sensors and software that can gauge and evaluate display performance for not just one but a whole network of monitors. This means you could hypothetically be in a totally different department and software will inform you that one of your monitors has gone out of whack. You could be in Tahiti and get an email telling you as much, if you really want that…

Here's a sampling of what display vendors and distributors were showing off on the exhibit floor, organized in alphabetical order.


Ampronix Imaging Technology provided information regarding some of its latest display offerings, highlighting the Dynamaxx 3D multiview lenticular display. This display is a full-color, large, 43-inch monitor that offers 3D viewing without special glasses and provides wide angle viewing for more than one person at a time. The Dynamaxx is able to switch back and forth between 2D and 3D images for multifunctional displaying. The high quality 3D imaging capability is made possible through an advanced graphics engine developed by Philips. Other features of the Dynamaxx are high lenticular resolution, off screen projection, and considerable depth of field.


Barco made a big splash at RSNA launching the next generation of its Coronis diagnostic display systems, available in various grayscale and color resolutions, with a number of advancements including ultra-bright color imaging; and unified luminance, among others. The company's towering "image wall" stopped a few passers by in the exhibit hall, too.

Barco's new Coronis line includes a 2 MegaPixel (MP) grayscale system, a 3 MP grayscale system, a 2 MP color system and a 3 MP color system featuring Barco's Diagnostic Luminance technology, which corrects luminance non-uniformities that are typical for traditional LCDs and backlights, assuring the displays remain uniformly DICOM-compliant, Barco says.
   
The color 3 MP Diagnostic Luminance technology is bundled with a high-performance, ATI-powered display controller. Based on PCI Express architecture, the display controller guarantees speedy and smooth image loading, roaming and manipulation in 2D and 3D.

Another innovation showcased was another addition to the Coronis Color 3 MP Diagnostic Luminance display system called the intelligent Ambient Light Compensation (ALC) system. ALC assures that the system remains DICOM-compliant under all lighting conditions by adapting its Look-Up Tables in response to ambient light conditions, the company says.

Featuring an integrated pedestal concept, the new Coronis enables customized multi-head configurations. Through this design, individual heads move and track as one integrated system.
   
Along with the Coronis, the company also introduced a new, web-based softcopy QA product, called Medical QAWeb. This software can be used in combination with the upgraded I-GUARD sensor which continually guards and adjusts the luminance output of the diagnostic viewing area. Thus, the new QA software provides an easy tool for calibration and QA, ensuring continuous diagnostic quality of the display.

Barco also announced the release of NIO Fusion 4MP at RSNA, a high-resolution large-screen color display system which is designed for PACS visualization throughout a hospital or within an OR. The NIO Fusion features a 30-inch screen surface and can seamlessly fuses two portrait 2 MP displays into one integrated desktop without a distracting bezel in the middle. The display system also includes 2560x1600 resolution and a wide screen format.

The NIO line also includes the DuoView mode which allows the displays to be integrated and fully compatible with legacy PACS. In this mode, the display is driven by two separate DVI video inputs, offering dual-head configuration with a resolution of 2 x 2 MP.

This large screen product line also is bundled with a high-performance, ATI-powered display controller. Additionally, the NIO Fusion 4MP includes Backlight Output Stabilization (BLOS) technology, which provides fast power-up and continuously stabilizes the luminance output of the system's backlight. This significantly improves the overall consistency of the display system. For local fine-tuning, the system also offers MEDICAL QAWEB, Barco says.


Double Black Imaging announced new front sensing color displays with calibration software, as well as FDA approval for an LCD for digital mammography applications. These displays are available through Double Black as the distributor and service provider for WIDE Corp. in North America.
   
Adding to its existing M-Series, the line now consists of a 2, 3, and 5 MP monochrome LCDs with a retractable front sensor and auto-calibration software. The Lumical Calibration Software monitors settings which can be handled at the client level or on the network and includes email notifications for display status. The front is able to emerge to run the DICOM grayscale calibration but retracts once the test is complete so as not to obstruct viewing. The LCDs also have integrated backlight sensors to monitor performance in any condition.
   
Double Black also highlighted the recent FDA approval of WIDE's 5 MP display system which has now been certified for use in digital mammography applications. The IF2105M is a 21.3 inch diagonal LCD driven by a high-speed graphic controller, the company says.
