基于腹腔镜虚拟现实的手术模拟器正在成为住院医师培训和评估的普遍工具。腹腔器官表面的血管是腹腔镜图像的主要视觉线索，因此开发血管生成算法具有重要意义。随机参数Lindenmayer系统（L-系统）制定的血管结构，可以纳入血管分支的生理规律。通过适当的重写规则和参数选择，它们可以表示不同器官的血管，并能反映生理系统的整体统计特征和局部随机特征。实验结果表明，该方法是可行和有效的。
Laparoscopic virtual reality based surgery simulators are becoming a ubiquitous tool in resident training and assessment. Blood vessels on abdominal organ surface are major visual cue of laparoscopic imagery, so it makes sense to develop algorithms of generation of blood vessels. Stochastic parameter Lindenmayer systems (L-systems) are formulated to generate blood vessel structures that can incorporate the physiological laws of blood vessel branching. With appropriate rewriting rules and choice of parameters, they can represent different organ blood vessels, and can exhibit the overall statistical character and the local stochastic character of the physiological system. Experiment results show that proposed method is feasible and effective.
