Figure 5From: Mathematical model of the anatomy and fibre orientation field of the left ventricle of the heartThe construction of the generating lines for a spiral surface corresponding to the conical LV with a thick vertex. The graph of the function ϕ (ρ) (see (14)) connects the points A and B for ϕ = 0 and ϕ = ϕmax by the line segments.Back to article page
