System-embedded diffusion bridges

anchor

Diffusion model constrained to respect the imaging system, used to generate edited scans that remain physically plausible. Supplies the counterfactual images that gSHNAP attributes over.

Findings

• SY-001Objects outside the patient, gown snaps and ECG electrodes, drive Sybil's risk predictions [primary]
• SY-002Sybil responds more weakly to nodules near the pleura, where adenocarcinoma tends to appear [primary]
• SY-003Sybil processes pulmonary nodules almost additively, with limited pairwise interactions [primary]
