FrequencyCT: Frequency Domain Self-supervised Low-dose CT Denoising 事件

FrequencyCT: Frequency Domain Self-supervised Low-dose CT Denoising arXiv:2605.10583v2 Announce Type: replace Abstract: Despite extensive research on computed tomography (CT) denoising, few studies exploit projection-domain data characteristics to mitigate noise correlation. To bridge this gap, this work proposes FrequencyCT, the first zero-shot self-supervised method for pseudo-sample generation in the frequency domain for low-dose CT denoising. Specifically, by exploiting the distinct frequen
