Knowledge-Based Multi-sequence MR Segmentation via Deep Learning with a Hybrid U-Net plus plus Model

The accurate segmentation, analysis and modelling of ventricles and myocardium plays a significant role in the diagnosis and treatment of patients with myocardial infarction (MI). Magnetic resonance imaging (MRI) is specifically employed to collect imaging anatomical and functional information about the cardiac. In this paper, we have proposed a segmentation framework for the MS-CMRSeg Multi-sequence Cardiac MR Segmentation Challenge, which can extract the desired regions and boundaries. In our framework, we have designed a binary classifier to improve the accuracy of the left ventricles (LVs). Extensive experiments on both validation dataset and testing dataset demonstrate the effectiveness of this strategy and give an insight towards the future work.
