Low-Dose CT for Stroke Diagnosis: A Dual-Pipeline Deep Learning Framework for Portable Neuroimaging

低剂量CT用于中风诊断:一种双管道深度学习框架用于便携式神经影像

Rhea Ghosal, Ronok Ghosal, Eileen Lou

机构 * Westlake High School(西湖高中) California Institute of Technology(加州理工学院) Round Rock High School(圆石城高中)

AI总结 本文提出双管道深度学习框架,用于低剂量CT中风诊断,在不同剂量水平上评估性能,发现直接分类在某些情况下更有效,建立了低剂量CT中风分诊的基准。

Comments 10 pages, 3 figures, 2 tables. Evaluation of direct classification and residual U-Net denoising followed by classification across five simulated photon-count levels and three deterministic noise seeds. Includes patient-cluster bootstrap confidence intervals. Uses the LDCT Classification dataset; motion and ring artifact experiments are outside the scope of this study
