L-systems for three-dimensional anatomical modelling: Towards a virtual laboratory in anatomy
L-systems are explored as a tool for the modelling of both branching and non-branching anatomical structures. Branching anatomical structures are modelled using parametric L-systems that are normally used to describe tree growth and structure. Non-branching structures are modelled using generalised cylinder L-systems. Both representations produce highly parametric models of the anatomy that can be used for efficient image generation and model matching. Examples are given to illustrate the power of this approach in modelling three-dimensional anatomy such as the ribcage, the lung airway, and the heart.
