The Texture-Shape Dilemma: Boundary-Safe Synthetic Generation for 3D Medical Transformers
This paper addresses the limitations of existing formula-driven synthetic data by proposing a Physics-inspired Spatially-Decoupled Synthesis framework that resolves the texture-shape conflict through a gradient-shielded buffer zone and spectral texture injection, thereby significantly enhancing the performance of 3D medical Vision Transformers on BTCV and MSD datasets without relying on real patient data.
