中文摘要: 本文针对医学脊柱CT图像因骨密度不均匀、骨骼结构复杂或图像成像分辨率低等因素造成的分割精度较低的问题, 提出一种基于卷积-反卷积神经网络的CT图像脊柱分割方法. 通过引入多尺度残差模块及注意力机制改进U-Net网络, 训练特征模型并进行测试. 在真实数据集上的实验结果表明, 该方法能有效提高CT图像中脊柱的分割精度及分割效率, Dice系数评估值为0.97, IOU系数评估值为0.94.
Abstract:Medical spine CT images have low segmentation accuracy due to uneven vertebral bone density, complex vertebral structure and low imaging resolution. To tackle these problems, this study proposes a segmentation method for spine CT images with a convolutional-deconvolutional neural network. The multi-scale residual module and the attention mechanism are introduced to improve the U-Net network, and the feature model is trained and tested. Experimental results on real data sets show that this method can effectively improve the accuracy and the efficiency of spine CT image segmentation. The estimated results of Dice coefficient and Intersection Over Union (IOU) are 0.97 and 0.94, respectively.
