FrequencyCT method enhances low-dose CT denoising via frequency domain analysis

Researchers have developed FrequencyCT, a novel self-supervised method for denoising low-dose CT scans by operating in the frequency domain. This approach leverages the frequency domain to separate noise from the actual signal, employing techniques like regional low-frequency anchoring and phase-preserving amplitude modulation. The method generates pseudo-labels for training without requiring clean data, showing promising results on public and real-world datasets and potentially revolutionizing CT denoising. AI

    FrequencyCT: Frequency domain pseudo-label generation for self-supervised low-dose CT denoising

    Despite extensive research on computed tomography (CT) denoising, few studies exploit projection-domain data characteristics to mitigate noise correlation. To address this, this work proposes FrequencyCT, the first zero-shot self-supervised method for pseudo-label generation in t…
