“…Pixelto-pixel [80] achieved image style transfer by training a conditional GAN whose generator and discriminator were both based on the input images. Many 3D medical applications take advantage of the conditional generative model, including conditional synthesis [33,109,140,148,215,219,220], segmentation [27,158,158,226,231], denoising [155,202,203,205,236], detection [59,147,188,208], and registration [11,154,230,234,238].…”
