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
