Researchers have introduced the Pixel-Level Residual Diffusion Transformer (PRDiT), a novel framework designed for generating high-resolution 3D CT medical volumes. This model employs a two-stage approach, first using an MLP-based denoiser for low-frequency structures and then a residual diffusion transformer with memory-efficient attention for high-frequency details. Experiments on LIDC-IDRI and RAD-ChestCT datasets show PRDiT surpasses existing methods like HA-GAN, 3D LDM, and WDM-3D in generating detailed and accurate medical imagery. AI
