English(EN) Multi-Stage Bi-Atrial Segmentation Framework from 3D Late Gadolinium-Enhanced MRI using V-Net Family Models

研究人员开发用于从 MRI 进行双心房分割的多阶段框架

作者 PulseAugur 编辑部 · [2 个来源] · 2026-04-29 03:13

研究人员开发了一种新的多阶段框架，用于从 3D MRI 扫描中分割双心房区域。该过程首先使用 MCLAHE 进行对比度增强的预处理步骤。随后，V-Net 系列模型对下采样图像进行粗分割，然后使用第二个 V-Net 模型对目标区域进行精分割。该框架利用不对称损失函数来优化模型训练。 AI

影响这项研究引入了一种新颖的医学图像分割方法，有可能提高心脏疾病的诊断准确性。
