摘要:

本文提出了一种全自动的方法来分割复杂的左心房(LA)腔,从三维钆增强磁共振成像(GE-MRI)扫描。该方法包括四个步骤:(1)预处理,将原始GE-MRI转换为概率图,(2)图谱选择,将图谱与目标图像匹配,(3)多图谱配准和融合,(4)水平集细化。该方法在MICCAI 2018 STACOM挑战赛提供的数据集上进行了评估,其中有100个数据集用于训练。与手动注释相比,所提出的方法实现了0.88的平均骰子重叠指数。

英文摘要:

This paper presents a fully automated method to segment the complex left atrial (LA) cavity, from 3D Gadolinium-enhanced magnetic resonance imaging (GE-MRI) scans. The proposed method consists of four steps: (1) preprocessing to convert the original GE-MRI to a probability map, (2) atlas selection to match the atlases to the target image, (3) multi-atlas registration and fusion, and (4) level-set refinement. The method was evaluated on the datasets provided by the MICCAI 2018 STACOM Challenge with 100 dataset for training. Compared to manual annotation, the proposed method achieved an average Dice overlap index of 0.88.
