Bringing digital visualization into the operating room

Bringing digital visualization into the operating room

Cydar, a joint spin-out company from King’s College London, Guys’ and St Thomas’ NHS Foundation Trust and the Guy’s and St Thomas’ Charity, was co-founded by Tom Carrell, a vascular surgeon in London and Graeme Penney, an imaging scientist at King’s College London.

Kings-SoR-IntroThe pair set out to solve a true clinical problem: the need for better visualization of the anatomy during endovascular surgery. They subsequently turned image processing research into a world first in cloud-based healthcare.

A £250,000 grant under Innovate UK’s (previously Technology Strategy Board) ‘SMART’ scheme funded a one-year project in which Cydar developed a prototype for real-time 3D overlays during an X-ray guided operation. The prototype, Cydar RTRS 1.0, was then trialled in four hospitals in the UK. Cydar RTRS 1.0, now Cydar EV, received a CE mark at the end of 2015.

The Cydar EV software works by continually scanning live X-ray images of the patient during surgery, using bony anatomy to detect the patient’s position and generate 3D overlays. Unlike mechanically-tracked systems, Cydar’s image-based tracking automatically corrects for errors caused by patient movement and differences in posture.

Cydar EV thus helps physicians to navigate through blood vessels and accurately and safely place a stent-graft in the patient. Previously, the only way to see blood vessels on the X-ray was to use an injection of potentially toxic contrast dye. Cydar provides a 3D image on top of the X-ray to enable physicians to see the blood vessels more clearly – guiding them in a similar fashion to the GPS navigation system typically used in cars.

Connecting live images from the operating room to the power of cloud computing opens up a world of possibilities not seen before in healthcare. It enables physicians to access the latest digital technology every time they work, bringing the diagnostic scan, the operative plan and the live image together in 3D.

For patients and staff, this can mean less time spent in the operating room and less exposure to radiation from X-rays. Patients also benefit from a lower dose of the X-ray contrast dye injected into their blood vessels, preventing potentially life-threatening complications.

“We are delighted that Cydar EV has now received a CE mark. This is fantastic news and will enable us to formally launch our 3D overlay software in Europe.”
