It wasn't all that long ago that the primary purpose of video screens or display systems in the operating room was simply to show the information and measurements gathered or registered be the arsenal of patient monitoring devices used in any given procedure. While video screens and display systems still play this very important part in the modern OR, they now have a far more important role; one that has developed out of and grown along with the recent shift toward minimally invasive surgery (MIS). Today, the surgical display system is among the most important medical devices in the OR, often giving the surgeon the only view of the surgical site he/she will have throughout an entire laparoscopic or endoscopic procedure. Fortunately, the views provided by the latest top of the line surgical scopes and imaging systems, projected on the surgical display systems, can provide the surgical team with clearer, brighter and better defined view of the surgical site than even open surgery.

In addition, the latest generations of surgical display systems are being developed to accommodate High-Definition (HD) technology, which is going even further to improve minimally invasive surgery. When one looks at the technology behind HD, the potential for improved surgical site visibility and other benefits to the surgeons quickly become obvious. In the most basic terms, HD provides the highest available resolution, thereby delivering a crisper and cleaner picture, providing the surgeons with a sharpness and detail closer to real life. Here is a look at some of the state-of-the-art surgical display systems that are changing the way surgery is seen in the modern OR.

Sony is a world leader in HD technology for the medical and surgical markets with high quality cameras, printers, displays and image capture units. Their innovative LMD-2450MD 24-inch (viewable area, measured diagonally) LCD (liquid crystal display) medical-grade widescreen display delivers full 1920 x 1080 HD resolution and boasts 10-bit signal processing and Sony ChromaTRU color balancing for superior detail, brightness and color accuracy. Designed for easy integration and operation in surgical environments, the LMD-2450MD is compatible with a full range of surgical mountings and features a front bezel control panel with touch-sensitive backlighting.

Designed for endoscopic, surgical reference and educational applications, the LMD-3250MD 32-inch LCD medical-grade widescreen display delivers full 1920 x 1080 HD resolution.
Recently added to Sony's extensive HD product line is the LMD-3250MD 32-inch LCD medical-grade widescreen display with full 1920 x 1080 HD resolution. Designed for endoscopic, surgical reference and educational applications, the monitor rounds out the robust Sony family of HD displays and upgrades the current top-of-the-line LMD-2450MD 24-inch model with an expanded viewing area and range of additional advanced features. Providing enhanced side-by-side image display, this new HD LCD supports simultaneous viewing of multiple modalities and maximizes use of the available screen space to significantly expand image size. Similarly, the picture-in-picture mode delivers larger inset images with enhanced space utilization.

Like the existing 24-inch display, the LMD-3250MD 32-inch LCD features 10-bit signal processing, Sony's ChromaTRU color balancing and a front bezel control panel with touch-sensitive backlighting. Plus, in dual monitor configurations, an innovative mirror image feature inverts the image display on one of the monitors to present clinicians, wherever situated, with an image orientation consistent with their view of the surgical field.

NDS Surgical Imaging, a company whose name is synonymous with surgical display systems, revolutionized the medical imaging industry with its development of the industry's first Digital Signal Processing (DSP) technologies for minimally invasive surgical viewing applications back in 1996. The company continues that tradition of innovation with technological and engineering advances in the fast growing surgical and PACS markets. NDSsi is a global leader in designing and manufacturing comprehensive medical imaging and informatics solutions for today's operative and interventional suites.

NDSsi pioneered the proprietary core technologies that enable surgical and diagnostic imaging to be viewed on the same HD compliant visualization systems. Advanced Imaging Processing (AIP), Digital Signal Processing (DSP) and related integration technologies allow simultaneous viewing of real-time video, fluoroscopic, ultrasound or vital sign imaging. Additionally, these technologies offer surgeons new capabilities as MIS and diagnostic imaging increasingly converge. NDSsi's AIP and DSP technologies encompass a number of proprietary features that work together to provide surgeons with superior clarity and precision images.

Expanding their already impressive and innovative product line, NDSsi in August of last year announced its acquisition of Dome Imaging Systems, the medical business unit of Planar Systems, Inc. Dome manufactures innovative medical display products for diagnostic imaging and patient care applications. Dome's customers include Picture Archiving and Communication Systems (PACS) OEM suppliers and leading medical Information Technology resellers to healthcare providers.

NDS Surgical Imaging currently offers the state-of-the-art, high-definition Radiance line of surgical displays in a variety of screen sizes ranging from 19 to 55 inches, as well as the full range of Dome PACS displays.

Stryker Endoscopy, a worldwide leader in high end imaging equipment and systems for use across a broad range of surgical specialties, had built upon its visualization expertise with the WiSe™ HDTV Flat Panel Monitor. This monitor, combined with the WiSe™ HDTV Transmitter, brings unique and innovative technological advancements and financial benefits to the OR. Uncompressed 1080p is transmitted wirelessly to eliminate cable clutter and potential costly repairs to flat panels. Token Keys create unique codes between monitor and transmitters to protect wireless signal quality from interference with other OR devices. WiSe™ HDTV will deliver optimal surgical images with most advanced resolution, brightness and optical clarity.
