HD Video from an Endoscopic Camera Facilitates Surgical Training

Cybermediacom launched in 2005 to meet businesses' growing need for video production, optimized for the Web. As an increasing number of entrepreneurs sought better exposure over multiple outlets, and the Internet in particular, our company has met that demand not only with video and consulting about how to optimize its online use, both on corporate websites and portals such as YouTube and Vimeo. For special projects, we also design and supply the hardware and software solutions required to capture, manipulate, and deliver quality video most effectively.
Matrox video processing products have played a key role in enabling some of our more innovative solutions. Among these is a solution we provide for a conference held by McGill University. The conference, "Gynecologic Cancer: Universal Access to Minimally Invasive Surgery," is hosted both by McGill University Gynecologic Oncology and The Society of Gynecologic Oncology of Canada. This first conference—in what is to be an annual educational event—featured the latest advances and up-to-date techniques in both advanced laparoscopic as well as robotic surgery for gynecological cancers. From the perspective of video delivery, this program also offered innovative production and broadcast of live video from two surgical sessions.
During this conference, we facilitated a broadcast from two operating rooms located at the Montreal General Hospital over a Bell Canada fiber optic link to the McGill University Health Centre, where it was shown in the Jeanne Timmins Amphitheatre at the Montreal Neurological Hospital. Using the Matrox Convert DVI HD-SDI scan converter in two different configurations, we provided a solution that gave 250 delegates the opportunity to witness world-class surgeons perform surgeries for a variety of gynecological cancers, using robotic or non-robotic approaches, performed side by side. The parallel live surgery demonstration was designed to help gynecologic oncologists to think about which approach they would choose.
The first operation was a laparoscopy in which the doctor manipulated the Storz HD camera himself. The camera output was fed through its proprietary receiver unit with a DVI output to the Matrox Convert DVI Plus. In the second operation, a robotic system—equipped with a Storz camera and imaging system—was connected to a control unit with a DVI output that was in turn fed to the Convert DVI Plus. The HD-SDI outputs from both of the Matrox DVI-to-HD-SDI converters were fed into a switcher that fed projectors to enable a large-scale broadcast with a picture-in-picture function used to highlight both procedures at once.
The Convert DVI Plus was the ideal solution for this demonstration because it offered both the flexibility and exceptional video quality required, and it happens to be very affordable, too. Because this was a critical training application based on the HD images being captured during delicate surgical procedures, we couldn't afford any degradation of the signal or distortion of the images. Another key benefit of working with the Convert DVI Plus was that we were able to preconfigure each system to operate as a stand-alone unit, so no on-site computer was needed.
In using a Matrox product, we got the added value of the company's support team, as well as confidence in the reliability and performance of the unit. I've been a Matrox user for years, so I know the company offers solid products that last. As the second annual gynecologic oncology conference approaches this fall, I'm sure we'll find yet another innovative use for the Convert DVI Plus.
