TL;DR利用基于小波的医学图像合成框架的扩散模型,可以在高分辨率下生成高质量的医学图像。
Abstract
Due to the three-dimensional nature of CT- or MR-scans, generative modeling of medical images is a particularly challenging task. Existing approaches mostly apply patch-wise, slice-wise, or cascaded generation techniques to fit the high-dimensional data into the limited GPU memory. However, these approaches may introduce artifacts and potentially restrict th
