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.
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.
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.
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.
Embracing the shift toward integration of high definition technology into the OR, Olympus (Orangeburg, NY) offers the EVIS EXERA II HD universal imaging platform, which provides physicians with a detailed, sharp and realistic image resulting from a higher pixel count and density. The system was designed specifically for endoscopic observation and minimally invasive surgery in the OR during Colonoscopy, Upper GI Endoscopy, Bronchoscopy, Laparoscopy and other procedures. With a single operating interface for all specialties, the universal imaging platform may increase efficiency by allowing endoscopy equipment to be deployed with more flexibility throughout the hospital.
The EVIS EXERA II imaging system delivers both HD and Narrow Band Imaging (NBI) technologies, which provide remarkably clear views of anatomical structures and fine capillary patterns of the mucous membranes that are normally difficult to distinguish. The imaging platform also offers HD compatible components throughout the entire imaging chain. The full system begins with the HD EndoEYE line of videoscopes, through the powerful HD processor and onto the HD LCD monitor for a true HD image. In the end, the system delivers 1080 lines of resolution.
In addition, the EVIS EXERA II platform when combined with Olympus’ HD Alpha OR integrated suite provides a definitive solution that facilitates optimal performance in the OR as it adapts to a broad array of surgical procedures by offering an HD video system that is also designed for all endoscopic applications. This allows facilities to take full advantage of new and future technologies as they continue to emerge.
All of these displays provide superior HD capabilities and sophisticated signal processing to produce sharp, accurate, true and bright images no matter what the source. They incorporate the latest technology, which allow for current needs as well as future capabilities.
The displays offered by Skytron meet or exceed the highest safety standards. They utilize fan-less cooling to prevent the introduction of contaminants into the sterile field. In addition, the membrane style buttons and non-dimpled enclosures ensure foreign matter will not accumulate into voids and possibly spread contaminants.
It seems there is no shortage of surgical display systems to provide surgeons with the optimal view of their surgical sites, but there is an important point to keep in mind in light of this increasing technology. Plan for the future. Technology is changing so rapidly, that the ability of a surgical display system to support the next generation of camera equipment may be its most valuable feature.
