From: Vascular tortuosity: a mathematical modeling perspective
a–d Tortuous segment of a left coronary artery. ω is measured at 24°. Based on this, the theoretical value of L/λ is 1.05 and of L/R is 2.64. For the vessel segment, calculated values of L/λ are 1.09 and of L/R are 2.61. This corresponds to absolute value errors of 3.67% in L/λ and 1.05% in L/R
