PET-Adapter improves PET image reconstruction with test-time domain adaptation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed PET-Adapter, a new framework designed to improve Positron Emission Tomography (PET) image reconstruction, particularly for limited-angle scans. This method allows pre-trained deep learning models to adapt to new clinical datasets without needing retraining or paired ground truth data. By incorporating layer-wise anatomical conditioning and a physics-informed warm-start, PET-Adapter significantly reduces the number of diffusion steps required for reconstruction while maintaining high image quality across various clinical scenarios.

    PET-Adapter: Test-Time Domain Adaptation for Full and Limited-Angle PET Image Reconstruction

    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 …
