Cor2Vox

Definition

Cor2Vox is a cortex-grounded generative framework designed for synthesizing realistic 3D brain Magnetic Resonance Images (MRI). It leverages high-resolution cortical surface priors to guide a diffusion process, enabling topologically faithful image generation with precise anatomical control.

At a glance

Executive summary

Cor2Vox is a new AI system that creates realistic 3D brain MRI scans by using detailed information about the brain's surface. This helps overcome problems like not having enough real scan data, especially for rare conditions, and ensures the generated images are biologically accurate, unlike simpler methods.

TL;DR

Cor2Vox generates realistic, anatomically precise synthetic brain MRI scans by using the brain's cortical surface as a guide, solving real-world data scarcity and quality issues.
