Surgery enters virtual world

25.10.2005


Hip replacement outcomes could become far more predictable thanks to a revolutionary virtual surgery system developed by European researchers.



The IST-funded MULTISENSE project combined virtual reality, force-feedback systems, tissue profiling and stereoscopic vision to create virtual patients that mimic the tissue of real patients. Surgeons can now perform a hip-replacement operation on a virtual copy of their real patient.

More importantly, after the virtual surgery doctors can get a read-out indicating the likely success of the operation. This is a major step forward for prosthetic orthopaedics.


"Right now, many implants fail, but for some of them we’ve no definite idea about why they fail," says MULTISENSE scientific coordinator Cinzia Zannoni, a researcher at CINECA. "The really unique aspect of MULTISENSE is that it will give an indication of if an implant in a particular patient will fail." Surgeons can then test another implant to determine if that has a better chance of success.

The key to the MULTISENSE system is the Muscular Modelling tool. This is a semi-automatic modelling function that takes data from CT scans to make a virtual reconstruction of an individual patients’ muscle tissue.

"We have to customise the system to model the tissue of the individual patient to get an accurate indication of the probable outcome before each virtual surgery," says Zannoni.

It’s a very advanced application of virtual reality. Up to now, most medical systems simply replicated specific conditions, like appendicitis, for educational uses. The MULTISENSE system is tailored to specific patients.

The Muscle Modelling system is tied to a haptic, or force-feedback, system. Medical haptics are a vast advance on the feedback system used in the joysticks of games consoles. These devices create the force and resistance of real tissue, so when surgeons make a cut they feel the sensation of real surgery.

Add to that a stereoscopic viewing system and doctors can see, and feel, the surgery during the planning stage.

The haptic and virtual reality systems can also be voice controlled using simple commands. "A doctor would say ’I’m cutting the skin’ or, ’I’m lifting the muscle’, and the haptic system will adjust the force and pressure to suit that stage of the operation," says Zannoni. It means the operation is as close to reality as is possible with current systems.

The system could prove very cost effective if it reduces the number of implant failures, particularly since predictions indicate that hip implants will grow with Europe’s ageing population.

In the future, MULTISENSE could also be adapted to work in Computer-Aided Surgery. "We designed our system to work at every stage of the operation, from planning to actual surgery. Right now it will be used only for planning the surgery, but if there is a need it could help doctors to perform operations, too."

This is a growing are in medical science, with doctors increasingly taking advantage of the precision of robotic arms, for example.

The system could also be used for other surgeries, though MULTISENSE currently has no plans to develop them. Currently surgeons are evaluating the prototype. Once that’s completed, Italian company SCS-B3C will commercialise the software and the system. The haptic research will be exploited by a British company,” says Zannoni.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
