AI synthesizes CT-equivalent images from low-dose scans for radiotherapy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a deep learning framework using a conditional denoising diffusion probabilistic model to synthesize CT-equivalent images from low-dose cone-beam CT (CBCT) scans. This approach aims to improve image quality for radiotherapy planning, reducing the need for repeated high-dose CT scans. The study specifically investigates whether using physics-aware CBCT representations, such as filtered back-projection (FDK) reconstructions, enhances the performance of diffusion-based CT synthesis compared to standard DICOM CBCT images.

    Toward CT-Equivalent Image Quality in Low-Dose Radiotherapy Planning: Conditional Diffusion-Based CBCT-to-CT Synthesis and the Impact of CBCT Input Representation

    arXiv:2608.08919v1 Announce Type: cross Abstract: During standard radiotherapy planning, repeated CT acquisitions are often required for patient registration, verification, and adaptive planning, resulting in increased cumulative X-ray dose. To mitigate this, low-dose cone-beam C…
