When Misalignment Becomes Supervision: Structured Label Noise in Supervised Synthetic CT Generation

Valentin Boussot, Cedric Hemon, Caroline Lafond +2

Supervised synthetic CT (sCT) generation is commonly trained and evaluated as voxel-wise regression against registered reference CT images. In practice, MRI-CT and CBCT-CT pairs ar…
