A Pilot Study on PET-to-CT Cross-Modal Translation: Systematic Validation of Brownian Bridge Diffusion Models

Cross-modal PET-to-CT translation is an important problem in medical image computing. PET encodes the functional distribution of a radiotracer, whereas CT encodes anatomical electron density, and the two are separated by a substantial modality gap. Existing approaches have well-known limitations: generative adversarial...
