CT image latent diffusion generation

Overview A generative model for creating 3D CT from Gaussian noise This bundle is for Nvidia MAISI (Medical AI for Synthetic Imaging), a 3D Latent Diffusion Model that can generate large CT images with paired segmentation masks, variable volume size and voxel size, as well as controllable organ/tumor size. The inference workflow of MAISI is depicted in the figure below. It first generates latent features from random noise by applying multiple denoising steps using the trained diffusion model. Then it decodes the denoised latent features into images using the trained autoencoder.
