This open access book bridges common tools in medical imaging and
neuroscience with the numerical solution of brain modelling PDEs. The
connection between these areas is established through the use of two
existing tools, FreeSurfer and FEniCS, and one novel tool, the SVM-Tk,
developed for this book. The reader will learn the basics of magnetic
resonance imaging and quickly proceed to generating their first FEniCS
brain meshes from T1-weighted images. The book's presentation concludes
with the reader solving a simplified PDE model of gadobutrol diffusion
in the brain that incorporates diffusion tensor images, of various
resolution, and complex, multi-domain, variable-resolution FEniCS meshes
with detailed markings of anatomical brain regions. After completing
this book, the reader will have a solid foundation for performing
patient-specific finite element simulations of biomechanical models of
the human brain.
