摘要:

深度学习已被证明在生物医学成像的许多任务中产生最先进的结果,特别是在分割方面。此外,从磁共振血管造影分割脑血管结构是一个具有挑战性的问题,因为其复杂的几何形状和拓扑结构具有很大的患者间变异性。因此,在这项工作中,我们提出了一个卷积神经网络的方法来解决这个问题。特别是,一个新的网络拓扑结构的灵感来自于U-net 3D和Inception模块,名为Uception。此外,关于稀疏数据的最佳目标函数的讨论也指导了项目期间的大多数选择。最先进的模型也实现了比较的目的和最终的结果表明,所提出的架构具有最佳的性能在这个特定的上下文中。

英文摘要:

Deep learning has been shown to produce state of the art results in many tasks in biomedical imaging, especially in segmentation. Moreover, segmentation of the cerebrovascular structure from magnetic resonance angiography is a challenging problem because its complex geometry and topology have a large inter-patient variability. Therefore, in this work, we present a convolutional neural network approach for this problem. Particularly, a new network topology inspired by the U-net 3D and by the Inception modules, entitled Uception. In addition, a discussion about the best objective function for sparse data also guided most choices during the project. State of the art models are also implemented for a comparison purpose and final results show that the proposed architecture has the best performance in this particular context.
