Aims and Objectives

                             This   project   aims   to   devise   and

                         validate  a uniquely effective fully parallel  surgery simulation tool for  use  in the

                          training, rehearsing and objective evaluation of surgeons to eradicate much of the

                          uncertainty   in   improving   existing   and   creating   new   surgical   procedures.   High

                          Performance   Computing   (HPC)   is   today   the   only   way   forward   to   simulate   the

                          effects   of   various   strategies   for   cutting   and   manipulating   brain   tissue   both

                          accurately and in real­time. Achieving this will provide a step­change in surgical

 Aim  The main long ­term aim of the research in which this studentship is inscribed is to  reconcile  

real­time and accuracy  in brain surgery simulation through cutting ­edge computational mechanics,

high­performance computing and realistic brain matter mechanical models. Achieving this aim is not

reasonably possible within a Ph.D.­level research, the proposed work will provide a detailed proof ­of­

concept required for further research by tackling the following four objectives.

Objectives   (1)  Optimise   accuracy   versus   computational   cost   through   cutting­edge   numerical  

methods (2) Develop and test massively parallel algorithms developed by leaders in HPC to achieve  

real­time   simulations  (3)  Utilise   rigorous   experimentally­informed   mathematical   models   of   brain  

tissue developed by world leaders in the field (4) Validate and verify the proposed simulation tool.

For the first time in the field of surgical simulation, the increased efficiency (objectives 1 and 2) will

allow realistic non­linear material models to be used (objective 3) without sacrificing accuracy.

What is there for you in this project?

Benefit to the student: Suitability of the project for training Through the unique HPC training, the

student will acquire cutting­edge skills in high­performance computing. By working closely with Lee

Margetts, and expert in HPC, the proposed project will allow him/her to build upon and hone these

skills beyond the MSc training. What is more, the proposed research is highly multi­disciplinary and

will  
train   the   Ph.D.   student   in   computational   biomechanics,  
which   is   a   leading   theme   in   today's research. More
specifically, two major sets of skills will be acquired:

Numerical methods for evolving discontinuities  [OpenXFEM++, FleXFEM, SB] XFEM is one of the

most highly researched fields in computational mechanics ­­5 articles in 1999­2000 and 74 in 2006­

2007 for a total of 138 journal papers between 1999 and 2008 (source: scirus) and more than 400

citations   of   the   original   paper   [8].   This   method   and   its   sibblings   such   as   the   Flexible   XFEM

(FleXFEM) is very likely to become an industrial standard in the coming decade. The student will join

SB's group, one of the most active and recognized developers of XFEM today both academically and

industrially, which will be essential in the transfer of his/her skills after the Ph.D.

Element­ by­ element   massively   parallel   architectures  [ParaFEM,   LM]   An   essential   point   for   this

research is that after his/her Msc, the training of the student in HPC will continue intensively, through

the   involvement   of   Lee   Margetts,   a   recognized   expert   in   massively   parallel   computing   and   an

experienced developer of HECToR supported packages. In particular, the student will be gradually

introduced to ParaFEM, developed and maintained by Lee Margetts.

Additionally,   the   student   will   benefit   from   the  
ongoing   work   of   the   team   of   Profs.   Ogden   and Holzapfel
in soft­tissue modelling and be exposed to some of the leading­edge
research by Prof. Ray

Ogden's group, of the host organisation, a world leading expert in fundamental theory in nonlinear

elasticity. These sets of skills are highly transferable and will provide the individual with a powerful

springboard for a successful career.
