Ultrasound Speckle Reduction Using Generative Adversial Networks [PDF]
2018 IEEE International Ultrasonics Symposium (IUS), 2018 Generative adversial networks (GANs) have shown its ability to create realistic and accurate image-to-image transformation. The goal of this work was to investigate whether deep convolutional GANs can learn to perform advanced ultrasound speckle reduction in real-time.
