Summary

• What is new: Introduction of the 3D Residual-in-Residual Dense Block GAN (3D RRDB-GAN) with a 2.5D perceptual loss function for improved 3D super-resolution in radiology imagery.
• Why this is important: The limited depth, clarity, and volumetric detail in 3D medical images, which hampers the effective interpretation and analysis of complex medical imagery.
• What the research proposes: The 3D RRDB-GAN model that incorporates a novel 2.5D perceptual loss function to significantly enhance the quality and realism of volumetric medical images.
• Results: Successful 4x super-resolution across diverse datasets, achieving superior quantitative metrics (LPIPS, FID) and qualitative improvements in image detail and realism.
