Conclusion: This study demonstrates the effectiveness of the DSBM model in enhancing mid-field MR image. Quantitative comparisons underscore the critical role of high-quality training data preparation. Our approach shows significant potential for its clinical application, particularly in scenarios where high-field MR imaging is essential but currently unavailable for upright treatment planning.
