The MDSC-1119 surgical display serves a broad range of applications for visualization in the OR.
In a big move for cable television, many channels are going digital with plans to start broadcasting in high definition. Of course, if you are still using the same 12-inch black and white television with the aluminum foil on the antenna that got you through college, you’re really not going to see any difference. For all of the high-end camera and broadcasting technology that is out there, in the end it really is the quality of the system on which you view it that makes all the difference. Yes, it’s all in the way you look at it.

This is especially true in the surgical arena. With more and more procedures being performed endoscopically and relying on precise and powerful cameras to provide a view of the surgical site, the display systems in the operating room can be among the most critically important equipment the surgeon uses. Fortunately, these surgical displays or monitors have been developing and advancing right along side of the cameras and computer equipment that provide the images they display. And thanks to the innovation and foresight of a number of imaging equipment companies, there are a variety of high-end display systems to choose from.

NDS Surgical Imaging offers high definition (HD) surgical imaging systems (pictured above and below) with a variety of multi-modality capabilities including picture-in-picture and split-screen imaging.
NDS Surgical Imaging offers high definition (HD) surgical imaging systems with a variety of multi-modality capabilities including picture-in-picture and split-screen imaging. The displays are provided in 19, 23, 32, 42 and 55-inch screen sizes and accommodate a broad range of minimally invasive surgical (MIS) procedures. They also employ state-of-the-art image processing technology, image-lag reduction electronics and crisp viewing applications to provide surgeons with superior, comprehensive HD medical imaging systems that are designed to meet any clinical application and configuration need.

The NDS HD surgical visualization systems support single or multiple modality imaging while remaining fully compliant for medical use in surgery. NDS 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. In addition, these technologies offer surgeons new capabilities to support future technological advancements as MIS and diagnostic imaging increasingly converge.

The AIP and DSP technologies from NDS encompass a number of proprietary features that work together to provide surgeons with high clarity and precision images. The Multiple Modality Imaging Processing™ (MMIP) feature accepts video and/or data from multiple outputs and integrates them into one seamless image for viewing, enabling the physician to view, toggle or swap a live or stored radiological image, locate an abnormality and perform the procedure with the highest level of precision. Image-Lag Reduction™ (ILR) incorporates advanced interpolation algorithms to deliver the industry’s fastest video response time with lag-free imaging, which greatly enhances accuracy in surgical navigation. And NDS’s Picture-Perfect Technology™ (PPT) eliminates the jagged edges that appear when interlaced video signals are displayed, this results in high image clarity and allows the precise positioning of instrumentation.

The NDS HD surgical display systems are also highly customizable, and adapted for boom-arm applications as well as integration into image-guided surgical systems. They offer advanced source selection sizing and swapping technologies and also advanced integration capabilities with image-guided surgical systems, robotic-assisted surgical systems, colonoscopy systems, computer-assisted surgical systems and computer-based fluoroscopic imaging systems.

Barco (Kortrijk, Belgium) offers a variety of surgical display systems to serve across the full spectrum of patient care. Their19-inch surgical LCD display, the MDSC-1119, with 1280 x 1024 resolution, provides full HD compatibility and is optimized for endoscopy viewing. The large screen LCD 42-inch and 47-inch HD native OR information displays deliver 1920 x 1080 resolution with full HD compatibility. Barco also offers a 30-inch 2560 x 1600 picture archiving and communication system (PACS) display that provides the option of bringing PACS to the operating room.

The MDSC-1119 surgical display serves a broad range of applications for visualization in the OR and can act as a multi-modality display. Major design efforts have been put toward video endoscopy in all the different analog and digital video standards, but the unit also allows the display of PACS images in DICOM, room and boom camera, patient monitoring information, ultrasound images and computer data.

Designed to be part of the modern, digital OR, the MDSC-1119 can be mounted on booms and remotely controlled via RS232. Its connectivity to a PACS workstation and ability to represent medical imaging in DICOM provide another advantage, as traditional light boxes for viewing X-rays on film in the OR are gradually becoming obsolete.

Barco surgical display systems utilize advanced video processing that results in better image quality in terms of detail, artifacts and image accuracy especially on analog video signals. They offer a 10-bit video channel as opposed to the 8-bit favored by many display systems currently in use, as well as less frame-delay in image processing. The displays also provide flexible Picture-In-Picture and Picture-by-Picture features that allow the free scaling, sizing and positioning of image windows, resulting in fully functional and versatile use of this feature.

STERIS’s surgical display systems support all industry-standard video signals right out of the box.
STERIS Corporation’s (Mentor, OH) surgical-grade high definition flat panel displays provide precise video images from endoscopic cameras, PACS, C-arms and other surgical imaging devices and cameras. They offer 32-inch to 42-inch large screen LCD flat panel monitors as well as surgical-grade HD flat panel displays. These displays utilize all broadcast-quality electronics for superior picture quality and essentially no image lag, and the available 1600 x 1200 pixel resolution enables them to take advantage of higher resolution cameras and image sources, resulting in sharper, clearer images.

An extremely convenient feature of the STERIS displays is that they support all industry standard video signals right out of the box, and the unique design behind the display systems allow them to accommodate new and emerging technologies, as they are not tied to one particular video technology. This is allows facilities to change endoscopic or imaging vendors due to a change in surgeons, an update in technology or any other reason without having to change monitors. An example of this is that STERIS has been including HD-SDI (a high-end, high definition video signal) on their displays for over two years, despite the fact that endoscopic and other cameras are only just now starting to utilize that technology.

The STERIS surgical displays feature a sealed, splash-proof aluminum case with no vent slots or cooling fans to trap or spread dust or contaminants. This also makes them easy to clean and extremely durable. Another unique feature is that professional-grade microphones are built directly into the monitor face for hands-free video conferencing or telephone. STERIS also provides suspension arms on which to mount the displays that actually help to optimize video capacity. Each arm is equipped with 12 armored fiber optic cables, nine video coaxial cables and multiple control and power wires in each suspension arm, providing complete flexibility and preparation for future technologies. In addition, STERIS offers a state-of-the-art video cable management system within the flat panel video suspension system. It utilizes a unique helix coil energy chain system to proactively manage and guide the cables within the arm. This reduces the chances of cable failure and extends the life of the cabling significantly.
