    Summary
    This summary is machine-generated.

    This study introduces a novel diffusion model, Prior Frequency-Guided Diffusion Model (PFGDM), for reconstructing limited-angle cone-beam computed tomography (LA-CBCT) images. PFGDM significantly improves image quality and preserves anatomical structures, enabling faster, lower-dose scans.

    Area of Science:

    • Medical Imaging
    • Radiotherapy Physics
    • Artificial Intelligence in Medicine

    Background:

    • Cone-beam computed tomography (CBCT) is crucial for image-guided radiotherapy.
    • Reconstructing CBCT from limited-angle acquisitions (LA-CBCT) is challenging due to severe under-sampling artifacts, posing an ill-posed inverse problem.
    • Diffusion models offer a promising approach for image reconstruction by learning data distributions.

    Approach:

    • Developed a Prior Frequency-Guided Diffusion Model (PFGDM) framework for robust and structure-preserving LA-CBCT reconstruction.
    • Utilized a conditioned diffusion model as a regularizer, incorporating high-frequency information from patient-specific prior CT scans as anatomical priors.
    • Introduced two variants, PFGDM-A and PFGDM-B, with distinct conditioning schemes to manage the influence of prior CT information during reconstruction.

    Key Points:

    • PFGDM-A applies prior CT high-frequency information until an optimized iteration, then drops it, accommodating anatomical variations.
    • PFGDM-B continuously applies prior CT information with a decaying mechanism, gradually reducing its influence.
    • Both PFGDM variants demonstrated superior performance over traditional and existing diffusion model-based methods in metrics like PSNR and SSIM.

    Conclusions:

    • PFGDM achieves high-quality LA-CBCT reconstruction even with very limited gantry angles.
    • The framework facilitates faster and more flexible CBCT scanning protocols.
    • This advancement contributes to significant radiation dose reduction for patients undergoing radiotherapy.
