摘要:

糖尿病足溃疡(DFU)是糖尿病的主要并发症,如果处理不当,可能导致截肢。DFU可以出现在足部的任何地方,并且可以根据各种病理而在大小,颜色和对比度上变化。目前DFU治疗的临床方法依赖于患者和临床医生的警惕性,这具有显著的局限性,例如DFU的诊断、治疗和长期护理所涉及的高成本。我们介绍了705个足部图像的数据集。我们提供了溃疡区域和周围皮肤的真实情况,这是临床医生评估溃疡进展的重要指标。然后,我们提出了一个两层的迁移学习从更大的数据集训练的全卷积网络(FCN)自动分割溃疡和周围的皮肤。使用5折交叉验证,所提出的双层迁移学习FCN模型对于溃疡区域实现了0.794($\pm$ 0.104)的Dice相似系数,对于周围皮肤区域实现了0.851($\pm$ 0.148)的Dice相似系数,并且对于两个区域的组合实现了0.899($\pm$ 0.072)的Dice相似系数。这证明了FCN在DFU分割中的潜力,可以通过更大的数据集进一步改进。

英文摘要:

Diabetic Foot Ulcer (DFU) is a major complication of Diabetes, which if not managed properly can lead to amputation. DFU can appear anywhere on the foot and can vary in size, colour, and contrast depending on various pathologies. Current clinical approaches to DFU treatment rely on patients and clinician vigilance, which has significant limitations such as the high cost involved in the diagnosis, treatment and lengthy care of the DFU. We introduce a dataset of 705 foot images. We provide the ground truth of ulcer region and the surrounding skin that is an important indicator for clinicians to assess the progress of ulcer. Then, we propose a two-tier transfer learning from bigger datasets to train the Fully Convolutional Networks (FCNs) to automatically segment the ulcer and surrounding skin. Using 5-fold cross-validation, the proposed two-tier transfer learning FCN Models achieve a Dice Similarity Coefficient of 0.794 ($\pm$0.104) for ulcer region, 0.851 ($\pm$0.148) for surrounding skin region, and 0.899 ($\pm$0.072) for the combination of both regions. This demonstrates the potential of FCNs in DFU segmentation, which can be further improved with a larger dataset.
