and the solid domains (B).
CAD objects can be added to the model. For example, an umbrella-like antenna
(Fig. 3.3B) could be useful in the study of tumor ablation procedures (van Sonnenberg
et al., 2010; Novanta et al., 2018).
In this case besides the antenna, an ellipsoid delimiting the tumoral tissue was also added.
3.2 Image-based reconstruction of anatomically accurate
computational domains
Numerical modeling in medicine and biology requires realistic computational domains
to obtain accurate results. This chapter introduces several examples where computed
