Elías Cueto, "Model order reduction methods for computational surgery"
Traditionally, surgeons have been trained to perform minimally invasive surgery with the help of animal or mechanical models. Nowadays computational mechanics, however, offer a unique opportunity to substitute these techniques by more sophisticated surgical simulators with haptic (force) feedback. The main difficulties of such an approach come from the fact that (i) soft tissues are strongly non- linear (usually modelled as hyperelastic), undergoing large displacements and strains and (ii) an accurate haptic feedback response must be provided at rates on the order of 1kHz. This means that we must be able to solve large strain, non-linear problems one thousand times per second. For realistic applications this still constitutes a challenge.
