The application discloses a kind of tumor angiogenesis simulation methods, including the blood vessel network topology including environment pixel point and blood vessel pixel point generated based on the medical image of patient;Based on the average path length and step length adjustment factor, chemotaxis weight, bifurcation number range and bifurcation probability of related data such as blood vessel tip of blood vessel network topology are constantly updated;And the bifurcation number of each iteration blood vessel tip and the branch length of each branch after bifurcation are calculated based on the update result of each iteration, and the update of blood vessel network topology is completed based on the bifurcation number and the branch length of each branch after bifurcation calculated, constantly circulate until reaching simulation condition.The application quantifies the transport efficiency of blood vessel network by global function index average path length, realizes the evaluation whether blood vessel network presents efficient local characteristics by clustering coefficient and average path length, guarantees that the blood vessel network obtained by simulation is same with real network.
