Printed Contrast Phantom Data

Imaging data sets for printed contrast phantoms across 4 timepoints and 3 frequencies. Printed contrast regions were analyzed for Backscatter signal within the region and CNR within the region compared to a background ROI.本数据集为覆盖4个时间点与3种频率的印刷式对比度体模成像数据集。针对各印刷对比度区域，分别分析其区域内的背散射信号（Backscatter Signal），以及该区域相较于背景感兴趣区（Region of Interest, ROI）的对比度噪声比（Contrast-to-Noise Ratio, CNR）。
