HD projection for ultrasound images

AUTHOR: Inavate

Insync Production implemented an ultra wide screen HD projection system at Hamburg’s 19th World Congress on Ultrasound in Obstetrics and Gynaecology. The system had to show ultrasound images in intricate detail and Insync used Christie projectors and Analog Way switching equipment for the event.

The International Society of Ultrasound in Obstetrics and Gynaecology (ISUOG) is an international professional membership association for ultrasound and imaging. Dedicated to furthering education and training, it has more than 3,200 members in 96 countries. In order to demonstrate the latest in ultrasound equipment, research and techniques to doctors and specialists from around the world, the ISUOG organises its World Congress annually in a different international location every year.

In 2009, the 19th World Congress on Ultrasound in Obstetrics and Gynaecology was held in Hamburg, Germany, from September 13 to 17, 2009. Over five days, more than 1,600 delegates explored the latest research and equipment in the field, thanks to live scan demonstrations of normal ultrasound findings by leading world experts, and interactive lectures.

Scott Tompkins, managing director of Insync Productions - the company chosen to handle technical production at the conference, said: “In order to offer new research presentations in obstetrics and gynaecology, the ISUOG required an ultra wide screen HD projection system.

“Traditional stage sets are easily replaced by bright, high definition visual backdrops with the ability to change appearance dramatically between sessions. Large images were required to give the 1,600 audience of Specialists the best possible view of the intricate detail being shown. It was also essential to have accurate contrast, a vital element when interpreting ultrasound images.”

He continued: “We needed the ability to connect a wide array of ultrasound and related imaging equipment to our Mixer Seamless Switcher using a wide variety of native input formats and resolutions. Picture in Picture (PIP) facility was also required in order to show both the output of the scan equipment along with the camera images from the backstage scan area and PowerPoint presentations.

“Instead of using a static large screen built into a traditional set, we installed a large 50ft x 15ft ultra wide screen back drop which effectively was the set. This allowed us to project PIPs of varying sizes and display multiple data sources at native resolution simultaneously, whilst ensuring that contrast levels be maintained at all times.”

Insync used four Christie HD10K-M projectors, Analog Way Di-VentiX II and Di-VentiX mixer seamless switcher, Analog Way Axion Multi Screen Event Controller, Analog Way iX Mate DVI Interface and two Analog Way Trident DVI Interfaces. Furthermore the company implemented two Samsung 23” Full HD LCDs, a 2-camera PPU kit (Inc Sony DSR570 Camera with Canon HJ40 lens), two Denon DVD players, a Teletest four-way LCD Monitor Bridge.

Tompkins continued: “Seamless Edge Blend technology and PIP offered many options to the client in terms of the way the material was presented. For example, during a live scanning, the video relay showing the consultant talking could be quite small and the actual scan image could be blown up to aid the best view possible. At other points in the presentation, the PIP would dissolve back into a more balanced view for images on one side and text on the other.

“We knew prior to the event that we would be presented with multiple video formats and resolutions which is why we selected the Analog Way products for this event. They allowed us to interface between ultrasound scan equipment, presentation laptops and the projection system. The Di-VentiX was used in the scan room backstage to provide one single output to the Di-VentiX II with all inputs catered for DVI-A, DVI-D, XGA, component and composite video all at a variety of resolutions. The product allowed us to work seamlessly with which ever format was requested on site by the scan equipment manufacturer. All laptops were also being fed into the Di-VentiX II.”

Tompkins concluded: “The flexibility in terms of functionality of the Analog Way solutions and their ability to interface with multiple source formats meant that we weren’t faced with any significant challenges on-site.”
