Dr. Sarju Ralhan is breaking new ground at the Hero DMC Heart Institute in Ludhiana, India. An internationally acclaimed surgeon with a focus in cardiovascular, thoracic and vascular surgery, he has a keen interest in the surgical management of patients afflicted with coronary artery disease and diseases of the aorta.

Having done over 5000 off-pump coronary artery bypass grafting (OPCABG) procedures, Dr. Ralhans specialty is total arterial grafting on a beating heart using bilateral internal thoracic arteries (ITA), the arteries that provide an important alternate blood supply if the native coronary arteries becomes obstructed. He performs the surgery using the rare procedure of just one incision to the chest. According to Dr. Ralhan, this method extends the surgery by 20 minutes but can add 20 years to the patients life expectancy.

Promoting the Procedure

Intent on promoting this new surgical method, Dr. Ralhan wanted to find an effective way to reach the public in general and specialized surgeons in particular. Given the busy schedules of his team and other healthcare professionals, watching the surgery live in the operating room was not always practical. Dr. Ralhan wanted a device that could record the procedures and provide straightforward access to the videos. To achieve this, he required high quality video delivery, recording capabilities, portability and ease of use.

Dr. Ralhan and his team evaluated many video capture devices but narrowed their search to the Matrox Monarch HDX, a H.264 dual-channel recording and streaming appliance, after consulting product reviews and a local distributor

A Surgical Solution

Using Monarch HDX, the workflow is very straightforward. Surgeries are filmed with a Luxtec headlight camera or a Nikon D810 camera. The Luxtec headlight camera outputs composite video which goes through a composite-to-SDI converter then into the Monarch HDX encoder. The Nikon D810 outputs an HDMI signal which goes directly to the Monarch HDX.

To stream the surgery, Monarch HDX sends an RTSP stream over the LAN at 2 Mbps. Dr. Ralhans staff can view the live stream directly from computers on the LAN or via Wi-Fi on their mobiles or tablets, all using VLC Player.

To record the surgery, the Monarch HDX is typically set to record at 25 Mbps to a USB drive or SD card. Monarch HDX provides the option to save files to a variety of recording media types, including a shared network drive, USB drive or SD card; so it is easy to store recordings in a way that works for everyone. The videos are reviewed and edited with Final Cut Pro X or Adobe Premiere before being made available to medical professionals on Dr. Ralhans YouTube channel and website. The surgical recordings are also provided to patients on a thumb drive.

Monarch HDX profiles simplify setup. Technicians use the Monarch HDX Command Center to initially select resolution, bitrate and all other streaming and/or recording parameters then to save a profile. In advance of a surgery any operator can easily choose one of the pre-configured profiles for a particular camera or destination, for example, and the parameters will be loaded automatically.

Technicians also take advantage of Monarch HDXs H.264 preview stream feature to view a low bitrate preview of the input directly in the Command Center before going live.

The Final Result

Since implementing the Monarch HDX into his workflow, Dr. Ralhan has found that this content delivery mechanism is quite easy and user friendly, and adds no additional cost. Viewers simply need to log in and open a VLC player on their device of choice to watch the latest surgeries in HD.

Expanding the Scope

Dr. Ralhan intends to use Monarch HDX to live stream surgeries to surgeons around the world. He hopes to have his surgeries featured on websites such as ORlive.com with the goal of getting young surgeons to use this technique more frequently. As of today, only my operating room staff members view the live streams, but I expect to live stream surgeries for workshops where I will have a broader audience.

TV Futures - Producers Produce
Emily Merritt I’ve learnt two major facts about being a producer since studying on my BSc Television and Broadcasting course: ‘the role of producer cannot be defined in a sentence’ and ‘if your team don’t see you working, you’re doing your role as producer correctly’.

What is the JT-NM Tested Program
Bruce Devlin - new The National Association of Broadcasters (NAB) Show 2019 has come and gone with the usual onslaught of product announcements, launch parties, demonstrations and the usual high-density crowds preventing any high-speed movement between halls. The IP showcase, this year, featured a JT-NM tested program. If you're unfamiliar with the JT-NM, then it's worth checking out their website jt-nm.org where you can find out about the work being done to coordinate the different aspects of building an inter-working ST 2110 eco-system. The JT-NM tested program catalogue can be downloaded from the website and it highlights a series of tests that were performed prior to NAB on various products to see how they performed against the written standards upon which the ST 2110 eco system is based.

State of the Nation - If Winter Comes
Dick Hobbs - new Here’s an important fact that might get lost in all the noise of the moment. HBO’s Game of Thrones, which is relentlessly covered in the press as well as being talked about by its fans, is not actually terribly popular. The opener of the current (and last, thank goodness) series attracted a consolidated audience of about 3.5 million – that includes 2.7 million who watched the first showing at 2am, plus those who watched it at a more civilised hour, or who recorded it. Informed comment seems to be that those who watch on catch-up at some time in the following week or so might add a million more.

Lighting with Gurdip Mahal
Ian Muir Gurdip Mahal’s credits for lighting design are impressive. Including major Awards shows such as BBC Sports Personality of the Year, Children in Need, as well as The Voice, Top Gear and Crystal Maze, his CV would almost certainly include at least one show with which any one of us is familiar. In addition, he has applied his own particular style to performances by major artists such as U2, Beyonce and Lady Gaga.
