AI model tackles PET/CT lesion segmentation challenge

Libo Zhang has developed a novel three-phase curriculum learning approach for interactive lesion segmentation in PET/CT scans, addressing the autoPETV Grand Challenge. This method utilizes a U-Net architecture with approximately 140 million parameters, trained over 4000 epochs. The curriculum progresses from fully automatic segmentation to learning from ground-truth-derived scribbles and finally adapting to its own errors through online correction simulation. The solution achieved strong results in cross-validation, demonstrating significant improvements with interactive correction steps. AI

IMPACT Introduces a new curriculum learning strategy for medical image segmentation, potentially improving diagnostic accuracy.
