English(EN) Novel Methods for Catheter and Guidewire Segmentation in X-ray Fluoroscopy under a Federated Learning Setting

联邦学习框架增强医学影像分割

开发了一个新的联邦学习框架,用于X射线透视图像中导管和导丝的分割,解决了血管内治疗中数据稀疏和隐私的挑战。该框架引入了一个名为CathAction的基准数据集,包含超过60万张标注帧。它结合了形状敏感的损失函数和对抗性优化技术,以提高分割精度,尤其是在异构客户端数据场景下。此外,一个结构感知扩散模型合成了逼真的视频序列,当将其集成到联邦训练中时,可以在数据稀疏的情况下显著提高分割性能。 AI

影响 这项研究可以通过对医学影像数据进行更准确的实时分析来提高血管内治疗的安全性和效率,同时不损害患者隐私。
