Diffusion Schr\"odinger Bridge Models for High-Quality MR-to-CT Synthesis for Head and Neck Proton Treatment Planning

arXiv:2404.11741v1 Announce Type: cross
Abstract: In recent advancements in proton therapy, MR-based treatment planning is gaining momentum to minimize additional radiation exposure compared to traditional CT-based methods. This transition highlights the critical need for accurate MR-to-CT image synthesis, which is essential for precise proton dose calculations. Our research introduces the Diffusion Schr\"odinger Bridge Models (DSBM), an innovative approach for high-quality MR-to-CT synthesis. DSBM learns the nonlinear diffusion processes between MR and CT data distributions. This method improves upon traditional diffusion …
