Abstract

En 中文

• Novel diffusion model for lung nodule synthesis in 3D thoracic CT scans. • Pulmonary DPM-solver is proposed to improve sampling efficiency. • Solving the common anatomical imprecision issues of SOTA generative models. • Up to 8× lower FLOPs, 6.8× lower GPU memory usage, 14× faster sampling compared to competitors. • Advanced performance in a radiologist-verified Visual Turing Test and segmentation tasks.
