RetinaDiff 使用少量帧的扩散模型改进视网膜成像

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-07 04:00

研究人员开发了 RetinaDiff，这是一个利用条件扩散模型改进视网膜激光散斑对比成像 (LSCI) 的新颖框架。该方法提高了运动鲁棒性，并且仅需要少量帧即可进行重建，克服了传统 tLSCI 需要更长序列的局限性。RetinaDiff 结合了相位相关性进行稳定化，并使用由运动校正先验引导的扩散模型来重建高质量图像。与现有方法相比，该框架在 SSIM、PSNR 和 FID 方面表现出显著的改进，即使在输入严重退化的挑战性案例中也是如此。 AI

影响这项研究将扩散模型应用于医学成像领域，有望提高视网膜血流监测的诊断准确性和效率。

面向运动鲁棒视网膜瞬态激光散斑对比成像的物理信息条件扩散模型

arXiv:2604.20594v2 Announce Type: replace Abstract: Retinal laser speckle contrast imaging (LSCI) is a noninvasive optical modality for monitoring retinal blood flow dynamics. However, conventional temporal LSCI (tLSCI) reconstruction relies on sufficiently long speckle sequences…
