Myofibre rotation angle definition (a), which is the angle between ${\mathbf{f}}_0^{\parallel }$ and c₀. ${\mathbf{f}}_0^{\parallel }$ (in-plane) and ${\mathbf{f}}_0^{\mathrm{\perp }}$ (out-of-plane) are the projections of f₀ in c₀ − l₀ and l₀ − r₀ planes, respectively, (b) AHA 17 segments definition in a bullseye view and (c) in the porcine model. Three different myofibre architectures are generated, they are (d) LDDMM derived, (e) RBM¹⁷ and (f) RBM^uni.
