摘要:

多模态医学图像可以为临床医生提供靶区(如肿瘤、器官或组织)的丰富信息。然而,由于多模态图像之间相互独立且仅有互补性,如何有效融合多模态图像并进行分割仍是亟待解决的问题。传统的图像融合方法难以有效解决此问题,因此基于深度学习的多模态医学图像分割算法得到了广泛的研究。从原理、技术、问题及展望等方面对基于深度学习的多模态医学图像分割任务进行了综述。首先,介绍了深度学习与多模态医学图像分割的一般理论,包括深度学习与卷积神经网络(CNN)的基本原理与发展历程,以及多模态医学图像分割任务的重要性;其次,介绍了多模态医学图像分割的关键概念,包括数据维度、预处理、数据增强、损失函数以及后处理等;接着,对基于不同融合策略的多模态分割网络进行综述,对不同方式的融合策略进行分析;最后,对医学图像分割过程中常见的几个问题进行探讨,并对今后研究作了总结与展望。

Abstract:

Multi-modal medical images can provide clinicians with rich information of target areas (such as tumors, organs or tissues). However, effective fusion and segmentation of multi-modal images is still a challenging problem due to the independence and complementarity of multi-modal images. Traditional image fusion methods have difficulty in addressing this problem, leading to widespread research on deep learning-based multi-modal medical image segmentation algorithms. The multi-modal medical image segmentation task based on deep learning was reviewed in terms of principles, techniques, problems, and prospects. Firstly, the general theory of deep learning and multi-modal medical image segmentation was introduced, including the basic principles and development processes of deep learning and Convolutional Neural Network (CNN), as well as the importance of the multi-modal medical image segmentation task. Secondly, the key concepts of multi-modal medical image segmentation was described, including data dimension, preprocessing, data enhancement, loss function, and post-processing, etc. Thirdly, different multi-modal segmentation networks based on different fusion strategies were summarized and analyzed. Finally, several common problems in medical image segmentation were discussed, the summary and prospects for future research were given.
