Visual and Quantitative Evaluation of Amyloid Brain PET Image Synthesis with Generative Adversarial Network

Abstract: Conventional data augmentation (DA) techniques, which have been used to improve the performance of predictive models with a lack of balanced training data sets, entail an effort to define the proper repeating operation (e.g., rotation and mirroring) according to the target class distribution. Although DA using generative adversarial network (GAN) has the potential to overcome the disadvantages of conventional DA, there are not enough cases where this technique has been applied to medical images, and in particu… Show more

“…The authors of [ 53 ] proposed a GAN for computed tomography (CT) to magnetic resonance image (MRI) data synthesis and translation. A conditional GAN was used for PET image synthesis [ 54 ]. A deep convolutional GAN (DCGAN) was recommended for image synthesis and the detection of liver cancer on X-ray and CT images [ 55 ].…”
