| 中文摘要: |
| 深度学习在医学影像分割领域吸引了广泛应用，其中2015年提出的U-Net因其分割小目标效果较好，结构具有可扩展性，自提出以来受到广泛关注.近些年来，随着医学图像割性能要求的提升，众多学者针对U-Net结构也在不断的改进和扩展，比如编解码器的改进，或是外接特征金字塔等.本文通过对基于U-Net结构改进的医学影像分割技术，从面向性能优化和面向结构改进两个方面进行总结，对相关方法进行了综述、分类和总结，并介绍图像分割中常用的损失函数、评价参数和模块，进而总结了针对不同目标改进U-Net结构的思路和方法，为相关研究提供参考. |

| The application of deep learning in the field of medical image segmentation has attracted great attentions, among which the U-Net proposed in 2015 has been widely concerned because of its good segmentation effect and scalable structure. In recent years, with the improvement of the performance requirements of medical image segmentation, many scholars are improving and expanding the U-net structure, such as the improvement of encoder- decoder, or the external feature pyramid and so on. In this paper, the medical image segmentation technology based on U-Net structure improvement is summarized from the aspects of performance-oriented optimization and structure-oriented improvement. Related methods are reviewed, classified and summarized. The paper evaluates the parameters and modules, and then summarizes the ideas and methods for improving the U-Net structure for different goals, which provides references for related research. |
