Fiber Optic RealShape (FORS) technology - sparking a new era in device visualization

As Philips, we are committed to helping caregivers treat their patients better. Playing a central role in the transition from open to minimally-invasive interventions was already a great step forward in this. Now we are on a research journey to further innovate image guided procedures.

We want to break through the current limitations of image guided therapy so clinicians can reduce their dependency on fluoroscopy while seeing intra-body devices ever-more clearly. 

 

In line with this ambition, our Fiber Optic RealShape (FORS) technology sparks a new era in image guidance. This unique technology enables real-time 3D visualization of the full shape of devices inside the body without the need for fluoroscopy.

Why push beyond the limitations of minimally invasive therapy?

 

As the transition from open surgery to minimally-invasive interventions continues, more and more procedures are being carried out using this approach. One consequence is that increasingly-complex interventions can take place in a minimally-invasive way. However, this also has a downside; longer procedure times, intense training programs, higher radiation exposure and an increased usage of contrast agent. All of which brings potential health risks to patients, physicians and staff. 

 

X-ray is considered the ‘gold standard’ for the imaging used to guide physicians during such interventions, because of its ability to visualize devices, in real-time, within the anatomy.  Yet navigation within complex anatomies remains a challenge, even when the 2D X-ray device visualization is combined with 3D anatomical information as an overlay.

 

As clinicians continue to expand their practice and strive for better and more effective ways to treat patients, there is a growing need for them to see devices in 3D, in real time, and in relation to the anatomy. At the same time, they want to reduce exposure to radiation for themselves, their staff and their patients.

 

At Philips, we have already made progress in tackling this visualization and radiation reduction need. Building on this experience – and after extensive dialogue with medical professionals on the frontline of this specialized area of healthcare – we concluded that something completely new was required. Not incremental innovation, but rather a breakthrough technology. One that opens up new possibilities in carrying out minimally-invasive procedures, standard or complex, through intuitive device and anatomy visualization in a radiation-free environment.

What is FORS?

Fiber Optic RealShape (FORS) is a ground-breaking technology platform which enables real-time 3D visualization of the full shape of devices inside the body, without the need for stepping on the fluoro pedal. 

 

This technology platform consists of equipment which sends pulses of light through hair-thin optical fibers that run within minimally invasive devices. This platform integrates with our Philips interventional X-ray systems.

 

The FORS technology has the following characteristics:

  • It displays the full shape of devices in 3D,
  • in real-time and in distinctive colors,
  • in multiple, user controlled, unrestricted viewing angles and
  • in context of the patient’s anatomy (using overlays from pre-operative 3D anatomical data or intra-operative X-ray imagery).

 

We are proud that following successful pre-clinical trials, we have concluded the FORS First Clinical Study. This first-in-human study was conducted at the University Medical Center of Utrecht, The Netherlands. The results were shared during the LINC congress in Leipzig, Germany. Please refer to the timeline to link to the presentations.

 

This is a major milestone on our research journey. Starting in Europe, selected partner hospitals are scheduled to participate in clinical studies in the coming months and years, with the initial focus on learning and perfecting our technology within vascular procedures.

How does FORS work?

Through FORS technology, devices are visualized inside the body using the ingenious application of light travelling through hair-thin optical fibers. The technology is based on the concept of measuring strain in optical fibers, using light reflected from density fluctuations in these fibers.

To achieve this, an optical fiber is integrated into intra-body devices. By sending laser light into this fiber and then analyzing how it is reflected back along the fiber, we can reconstruct and visualize the full shape of the devices. In 3D. In real time. In distinctive colors. And from any viewing angle. 

 

These intra-body devices can be shown in the context of the patient’s anatomy through integration with images obtained by conventional pre- or intra operative techniques (CT, MRI and X-ray fluoroscopy respectively). Clinicians can therefore see with clarity where and how they need to navigate and position their devices within the anatomy.

 

FORS is a prime example of how we have combined our optics and device legacy with our image guidance expertise to create a technology that is at the intersection of imaging guidance and therapy.
