GRIDiron: An Interactive Authoring and Cognitive Training Foundation for Reconstructive Plastic Surgery Procedures
ACM Transactions on Graphics (SIGGRAPH Proceedings), Volume 34 (4), page 43:1--43:12 — jul 2015
We present an interactive simulation framework for authoring
surgical procedures of soft tissue manipulation using
physics-based simulation to animate the flesh. This interactive
authoring tool can be used by clinical educators to craft
three-dimensional illustrations of the intricate maneuvers involved
in craniofacial repairs, in contrast to two-dimensional
sketches and still photographs which are the medium used
to describe these procedures in the traditional surgical curriculum.
Our virtual environment also allows surgeons-intraining
to develop cognitive skills for craniofacial surgery
by experimenting with different approaches to reconstructive
challenges, adapting stock techniques to flesh regions
with nonstandard shape, and reach preliminary predictions
about the feasibility of a given repair plan. We use a Cartesian
grid-based embedded discretization of nonlinear elasticity
to maximize regularity, and expose opportunities for
aggressive multithreading and SIMD accelerations. Using a
grid-based approach facilitates performance and scalability,
but constrains our ability to capture the topology of thin surgical
incisions. We circumvent this restriction by hybridizing
the grid-based discretization with an explicit hexahedral
mesh representation in regions where the embedding mesh
necessitates overlap or nonmanifold connectivity. Finally, we
detail how the front-end of our system can run on lightweight
clients, while the core simulation capability can be hosted on
a dedicated server and delivered as a network service.
