New VoxStruct3D framework generates high-fidelity 3D MRI scans

Researchers have introduced VoxStruct3D, a novel framework for generating high-fidelity 3D MRI scans directly in voxel space. This method utilizes a Volumetric Voxel Generator (VVG) that combines factorized 3D patch embedding with overlapping upsampling and time-modulated residual refinement to improve anatomical coherence and reduce artifacts. Additionally, a Structure-First, Image-Follows (SFIF) strategy incorporates a frozen 3D medical encoder to extract compact structure tokens that guide the image generation process, leading to superior performance in feature-distribution alignment, sample diversity, and perceptual quality.
