A Pulmonary Artery-Vein Separation Algorithm Based on the Relationship between Subtrees Information

Figure 5

Schematic diagram of the pulmonary vascular geometric graph representation: (a–d) centerlines reconstructed based on Dataset 1 (a, b) and Dataset 2 (c, d), among which a and c are right lungs, and b and d are left lungs; (e–h) horizontally corresponding geometric graph representation; (i–l) graphic details of corresponding representations; (m–p) subtree separation results.
