Prior-Enhanced Axial TransUNet: integrating MedSAM priors and sparse region-aware attention for kidney-tumor segmentation

Accurate kidney and renal-tumor segmentation is challenging because lesion size, location, morphology, and boundary contrast vary substantially across abdominal CT scans. Most existing methods rely on a single form of local evidence and struggle to recover the boundaries of small lesions while maintaining global anat...
