English(EN) PET-Adapter: Test-Time Domain Adaptation for Full and Limited-Angle PET Image Reconstruction

PET-Adapter通过测试时域自适应改进PET图像重建

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了PET-Adapter，一个旨在改进正电子发射断层扫描（PET）图像重建的新框架，特别是在有限角度扫描方面。该方法允许预训练的深度学习模型适应新的临床数据集，而无需重新训练或配对的真实数据。通过结合层级解剖学条件和物理信息热启动，PET-Adapter显著减少了重建所需的扩散步数，同时在各种临床场景中保持了高质量的图像。 AI

影响 通过使AI模型能够适应不同的临床数据而无需重新训练，提高了医学成像的质量和效率。

    PET-Adapter：全角和有限角PET图像重建的测试时域自适应

    Positron Emission Tomography (PET) image reconstruction is inherently challenged by Poisson noise and physical degradation factors, which are further exacerbated in limited-angle acquisitions. While deep learning methods demonstrate promising performance, their generalization to …
