Live Surgery in 3D!

3D Live Surgery

When most people think of 3D video, big blockbuster movies come to mind. 3D-TV has not really penetrated the home market as quickly as HD for example. Most of the content available to home viewers is produced content, not live video. As a live transmission company, producing a live 3D broadcast presented a lot of challenges in uncharted waters. DCI recently worked with Boxline Box medical communications to transmit the first-ever live broadcast of a 3D surgery at the American Urology Association (AUA) annual convention in San Diego, CA. While most medical broadcasts are done via videoconference, Boxline’s highly experienced Operating Room video staff and DCI’s quality-obsessed field uplink engineers combine perfectly to produce the best looking live broadcasts in the medical communications industry.

The AUA conference includes a lot of live video from the daVinci robotic surgical system, which natively works in 3D for the surgeon doing the procedure. All the previous feeds we have done were all standard 2D HD, but this year we stepped it up a level to provide the same 3D HD video seen by the operating surgeon.

Because the data required to carry uncompressed 3D HD video exceeds the 1.5gbps defined in SMPTE-292M, commonly known as HD-SDI, there are two ways to carry this content. SMPTE 424M is the most simple within a production plant, it uses a single coaxial cable with a data rate of around 3.0gbps. This interface is commonly referred to as 3G-SDI, although the “G” stands for gigabit, not “Generation” as 3G cellular standards. The only problem with 3G-SDI is very few HD encoders and receiver/decoders used by satellite trucks and teleports are capable of handling it, and the few that do require expensive license keys which no one has purchased due to the lack of 3D transmission requests.

Brain surgeons get a practice run with simulator from Elyria-based Surgery Theater

For a number of years, pilots have used virtual reality simulators to practice critical missions before taking to the skies. Thanks to a revolutionary new virtual reality training tool developed by Elyria’s Surgical Theater, LLC, surgeons now have a way to practice brain surgery before setting foot in the operating room.

The Surgery Rehearsal Platform (SRP) simulator consists of a desk top computer, a portable laptop system, software, controllers and 3D glasses.

“Using standard CT and MRI images from any patient, the SRP generates accurate models in 3D that show the interaction between life-like tissue and surgical instruments,” explains Moty Avisar, Surgical Theater president and CEO. “The tissue responds realistically to actions taken by the surgeon, enabling pre-surgery planning and rehearsal with complete accuracy.”

Beyond practicing on standard CT and MRI images, surgeons can also use unique images taken of the patient who will be undergoing surgery.

Cutting Edge: 3D Tech Boosts Surgical Precision

Moviegoers aren't the only ones wearing 3D glasses nowadays — doctors could benefit from them, too, a new study suggests.

In the past, doctors have been skeptical of using 3D technology in their work, preferring to rely on their own experience. But that may change, thanks to improved 3D glasses and even glasses-free systems. Funded by industry sponsors, the study of 50 surgeons using the new technology showed improvements in surgical precision and speed.

"While the technology still requires some fine-tuning, technology without the need to wear special glasses will increase the popularity of 3D systems in operating rooms," study leader Ulrich Leiner of the Fraunhofer Heinrich Hertz Institute (HHI) in Berlin said in a statement.

Improvements to screens are driving developments in 3D technology. High-definition screens are already available. The next step is ultra-high definition, with a sixteenfold improvement in resolution, according to study co-author Michael Witte of HHI.

To evaluate whether new 3D technology was ready for hospital applications, researchers invited surgeons from the Klinikum rechts der Isar's surgical hospital to test it out. A leading endoscope manufacturer and an international display company funded the study.

The surgeons tested four different systems: 2D, 3D with glasses, 3D without glasses and a mirror-based 3D system. The glasses-free model relied on an eye-tracking camera system that delivered separate images to each eye, creating a 3D effect in the brain.
