Recently, research into deep-learning image reconstruction has started to look into using unsupervised diffusion models, trained only on high-quality medical images (ie without needing paired scanner measurement data), for modelling this prior understanding. Image reconstruction algorithms incorporating ...

The paper covers modern approaches to the evaluation of neoplastic processes with diffusion-weighted imaging (DWI) and proposes a physical model for monitoring the primary quantitative parameters of DWI and quality assurance. Models of hindered and restr
Existing CT image standardization models predominantly utilize GAN-based supervised or semi-supervised learning, but their performance remains limited. We present DiffusionCT, an innovative score-based DDPM model that operates in the latent space to transform disparate non-standard distributions into a ...
Denoising diffusion models embody a type of generative artificial intelligence that can be applied in computer vision, natural language processing and bioinformatics. In this Review, we introduce the key concepts and theoretical foundations of three diffusion modelling frameworks (denoising diffusion probabili...
《Solving inverse problems in medical imaging with score-based generative models》是一个同期进行的工作,但提供了一个更灵活的框架,不需要配对的数据集进行训练。通过在医学图像上训练的扩散模型,这项工作利用了物理测量过程,并专注于采样算法,以创建与观察到的测量和估计的数据先验一致的图像样本。R2D2+将基于扩散...

Diffusion probabilistic models in particular have generatedrealistic images from textual input, as demonstrated by DALL-E 2, Imagen andStable Diffusion. However, their use in medicine, where image data typicallycomprises three-dimensional volumes, has not been systematically evaluated.Synthetic images may...
