Figure 4From: Mathematical model of the anatomy and fibre orientation field of the left ventricle of the heartOn the left: The construction of the generatrices for a spiral surface, corresponding to the conical LV with a dot vertex. The graph of the function ϕ (ρ) (see (12)) connects the points A and B for ϕ = 0 and ϕ = ϕmax by the line segments. On the right: The resulting pseudoconus.Back to article page
