基于生成对抗网络的合成磁共振图像

Synthetic Magnetic Resonance Images with Generative Adversarial Networks

Antoine Delplace

摘要:

数据增强对于医学研究至关重要,可以增加训练数据集的大小并获得更好的结果。在这项工作中,我们实验三个GAN架构不同的损失函数,以产生新的大脑MRI。结果表明,超参数调整的重要性,并使用小批量相似层的鉴别和梯度惩罚的损失函数,以实现高质量和现实的收敛。此外,需要大量的计算时间来从原始数据集生成无法区分的图像。

英文摘要:

Data augmentation is essential for medical research to increase the size of training datasets and achieve better results. In this work, we experiment three GAN architectures with different loss functions to generate new brain MRIs. The results show the importance of hyperparameter tuning and the use of mini-batch similarity layer in the Discriminator and gradient penalty in the loss function to achieve convergence with high quality and realism. Moreover, huge computation time is needed to generate indistinguishable images from the original dataset.
