NVIDIA NIM for MAISI

MAISI (Medical AI for Synthetic Imaging) is a state-of-the-art three-dimensional (3D) Latent Diffusion Model designed for generating high-quality synthetic CT images with or without anatomical annotations. This AI model excels in data augmentation and creating realistic medical imaging data to supplement limited datasets due to privacy concerns or rare conditions. It can also significantly enhance the performance of other medical imaging AI models by generating diverse and realistic training data.

This container, which includes the MAISI model, is powered by NVIDIA NIM, part of NVIDIA AI Enterprise. This integration offers a suite of easy-to-use microservices designed to accelerate the deployment of AI models, like MAISI, across cloud, data centers, and workstations.

Key Features of MAISI:

• Generates high-resolution 3D CT images up to 512 × 512 × 768 voxels
• Supports variable voxel sizes ranging from 0.5mm to 3.0mm
• Capable of annotating up to 127 anatomical classes, including organs and tumors
• Allows controllable anatomy size for 10 specific classes
• Produces paired segmentation masks

By providing these capabilities, MAISI is a valuable tool for researchers advancing AI applications in healthcare. However, it is important to note that this model is intended for research purposes only and not for clinical usage.
