Key Research Interests

My research interests are in medical visualisation, surgical navigation and simulation, physics simulation and biomechanics. In the broader context this encompasses computer graphics, computer animation, computer vision, mechanics, virtual and augmented reality (VR/AR), finite element analysis (FEA) and numerical methods.

Below are a number of links to projects I have been working on:
 

  • Surgical Navigation -  We developed a hardware/software platform, called ARView,  for image enhanced (augmented reality) surgical navigation. This is in particular aimed at ENT (Ear, Nose and Throat) surgery where the stereoscopic surgical microscope and the rigid sinus endoscope are used as intra-operative imaging devices.
     
  • Medical Visualisation -  In collaboration with Dr. Roger Rowland from RMR Systems we developed 3DView which is a software solution aimed at the rendering and post-processing of medical image data from different modalities (X-ray CT, MRI, PET). This is an ongoing project and additional features are frequently added.
     
  • Surgical Simulation - We use advanced computer graphics solutions with hardware acceleration, explicit finite element (FE) algorithms and haptic feedback to simulate open surgery procedures. In this context, we have also performed a series of in-vitro experiments on human skin to assess its hyper- and visco-elastic properties.
     
  • Human Childbirth Biomechanics - We have studied fetal head moulding using finite element analysis and more recently investigated the effect of forceps delivery on the fetal head and the biomechanics of shoulder dystocia.
     
  • Vehicle Dynamics - VPEX
     
  • Trotting Horse
