Simulating the Seldinger Technique (2006-10)
The Seldinger Technique is used by interventional radiologists to introduce a guidewire and catheter into a patient's vascular system. This EPSRC funded project produced a simulator to help train this procedure. It was a project with the Collaborators in Radiological Interventional Virtual Environments (CRaIVE) consortium led by Derek Gould, a consultant interventional radiologist at the Royal Liverpool Hospital. The multidisciplinary team included experts from Bangor, Manchester, Leeds, Imperial and Hull universities.
Our Seldinger simulator combined two haptic devices: vessel puncture with a virtual needle and catheter and guide wire manipulation (Luboz, Hughes, Gould, John, & Bello, 2009). The latter is depicted in the image above. The simulation software displays the instrument interactions with the vessels. Instruments are modelled using a mass-spring approximation, while efficient collision detection and collision response allow real time interactions.
