论文摘要
冠状动脉疾病(CAD)是全球最常见的死亡原因,其诊断通常基于磁共振成像(MRI)序列的手动心肌分割。由于手动细分很繁琐,耗时且适用性较低,最近对使用机器学习技术的自动心肌进行了分割,最近已广泛探索。但是,几乎所有现有的方法都独立处理输入MRI序列,该序列无法捕获序列之间的时间信息,例如,序列中心肌的形状和位置信息随着时间的推移。在本文中,我们提出了一个心肌分割框架,用于左心室腔,右心室和心肌的心脏MRI(CMR)扫描图像。具体而言,我们建议将常规网络和经常性网络组合在一起,以在序列之间合并时间信息,以确保时间一致。我们评估了关于自动心脏诊断挑战(ACDC)数据集的框架。实验结果表明,我们的框架可以提高骰子系数2%的分割精度。
Coronary artery disease (CAD) is the most common cause of death globally, and its diagnosis is usually based on manual myocardial segmentation of Magnetic Resonance Imaging (MRI) sequences. As the manual segmentation is tedious, time-consuming and with low applicability, automatic myocardial segmentation using machine learning techniques has been widely explored recently. However, almost all the existing methods treat the input MRI sequences independently, which fails to capture the temporal information between sequences, e.g., the shape and location information of the myocardium in sequences along time. In this paper, we propose a myocardial segmentation framework for sequence of cardiac MRI (CMR) scanning images of left ventricular cavity, right ventricular cavity, and myocardium. Specifically, we propose to combine conventional networks and recurrent networks to incorporate temporal information between sequences to ensure temporal consistent. We evaluated our framework on the Automated Cardiac Diagnosis Challenge (ACDC) dataset. Experiment results demonstrate that our framework can improve the segmentation accuracy by up to 2% in Dice coefficient.
