Comparison of MR-IPT and IPT restorations across different undersampling settings. This figure evaluates the performance of MR-IPT against the original Image Processing Transformer (IPT) under both fine-tuned and zero-shot scenarios. Results in the green block represent fine-tuned comparisons, where both IPT and MR-IPT were trained on 4× and 8× undersampling with Cartesian random and Cartesian equispaced masks. Results in the yellow block illustrate zero-shot comparisons, where models were tested without additional fine-tuning. The results demonstrate that MR-IPT consistently outperforms IPT, achieving higher restoration fidelity, better structural preservation, and reduced artifacts, highlighting its superior adaptability and generalization capabilities.
