Relationship between (Rc/Rmax)×(Ds/Dmax)4 and normalized crown length (Lc/Lmax) in the asymmetric entire (A) LAD, (B) LCx, and (C) RCA trees of pig, which include 946,937, 571,383, and 836,712 stem-crown units, respectively. (D–F) Relationship between Rc/Rs and Lc/Ls in the LAD, LCx, and RCA trees of pig corresponding to (A–C).

(A) Corresponding to Table 1, the relationship between (Rc/Rmax)×(Ds/Dmax)4 and normalized crown length (Lc/Lmax) in the symmetric vascular tree for various species (16,18–29). (B) Corresponding to A, the relationship between Rc/Rs and Lc/Ls.

4. Figure 3
A comparison of (Ks/Kc)ML from the nonlinear regression of anatomical data and (Ks/Kc)EQ based on equations Ks=128μ/π and Kc=Rmax×Dmax4/Lmax. The comparison can be represented as (Ks/Kc)EQ=A×(Ks/Kc)MLB. When A is constrained to be 1 in the Marquardt-Levenberg algorithm, B has a value of 1 (R2 = 0.983).

5. Figure 4
(A) Relationship between (Rc/Rmax)×(Ds/Dmax)4 and normalized crown volume (Lc/Lmax) in the LAD, LCx, and RCA epicardial trees of pig with diameter of mother vessels larger than 1 mm, which include 132, 90, and 192 vessel segments, respectively. (B) Relationship between Rc/Rs and Lc/Ls in the LAD, LCx, and RCA epicardial trees of pig corresponding to A.
