AI总结:

针对闭源模拟器和真实数据稀缺问题,本文提出开源血管内介入模拟器 CathSim,验证其可高保真模拟真实机器人,并基于专家轨迹训练多模态导航网络以加速自主导管研究。

摘要:

血管内机器人在学术界和工业界都得到了积极开发。然而,由于闭源模拟器和物理模体的广泛使用,自主导管插入的进展往往受到阻碍。此外,由于医疗手术成本高昂,利用血管内机器人获取用于训练机器学习算法的大规模数据集通常不可行。在本章中,我们介绍了 CathSim,这是首个用于血管内介入的开源模拟器,旨在解决这些限制。CathSim 强调实时性能,以支持学习算法的快速开发和测试。我们针对真实机器人对 CathSim 进行了验证,结果表明我们的模拟器能够成功模拟真实机器人的行为。基于 CathSim,我们开发了一个多模态专家导航网络,并证明了其在下游血管内导航任务中的有效性。大量实验结果表明,CathSim 有潜力显著加速自主导管插入领域的研究。我们的项目已公开发布于 https://github.com/airvlab/cathsim。

英文摘要:

Endovascular robots have been actively developed in both academia and industry. However, progress toward autonomous catheterization is often hampered by the widespread use of closed-source simulators and physical phantoms. Additionally, the acquisition of large-scale datasets for training machine learning algorithms with endovascular robots is usually infeasible due to expensive medical procedures. In this chapter, we introduce CathSim, the first open-source simulator for endovascular intervention to address these limitations. CathSim emphasizes real-time performance to enable rapid development and testing of learning algorithms. We validate CathSim against the real robot and show that our simulator can successfully mimic the behavior of the real robot. Based on CathSim, we develop a multimodal expert navigation network and demonstrate its effectiveness in downstream endovascular navigation tasks. The intensive experimental results suggest that CathSim has the potential to significantly accelerate research in the autonomous catheterization field. Our project is publicly available at https://github.com/airvlab/cathsim.
