摘要:

由于大脑解剖结构复杂且病灶特性各异,利用磁共振成像(MRI)对脑卒中病灶进行准确分割存在诸多困难。本研究提出了Neuro-TransUNet框架,该框架将U-Net的空间特征提取能力与SwinUNETR的全局上下文处理能力协同结合,并通过先进的特征融合与分割合成技术进一步增强。全面的数据预处理流程提升了框架的效率,包括重采样、偏置场校正和数据标准化,从而提高了数据质量和一致性。消融研究证实了U-Net与SwinUNETR的深度集成以及数据预处理流程对性能的显著影响,并证明了该模型的有效性。所提出的Neuro-TransUNet模型使用ATLAS v2.0训练数据集进行训练,其性能优于现有的深度学习算法,在脑卒中病灶分割领域建立了新的基准。

英文摘要:

Accurate segmentation of the stroke lesions using magnetic resonance imaging (MRI) is associated with difficulties due to the complicated anatomy of the brain and the different properties of the lesions. This study introduces the Neuro-TransUNet framework, which synergizes the U-Net's spatial feature extraction with SwinUNETR's global contextual processing ability, further enhanced by advanced feature fusion and segmentation synthesis techniques. The comprehensive data pre-processing pipeline improves the framework's efficiency, which involves resampling, bias correction, and data standardization, enhancing data quality and consistency. Ablation studies confirm the significant impact of the advanced integration of U-Net with SwinUNETR and data pre-processing pipelines on performance and demonstrate the model's effectiveness. The proposed Neuro-TransUNet model, trained with the ATLAS v2.0 \emph{training} dataset, outperforms existing deep learning algorithms and establishes a new benchmark in stroke lesion segmentation.
