X-ray Tomography of Surgical Face Mask

The surgical mask sample was scanned by lab-based X-ray micro-scale CT scanner (Zeiss Xradia 620 Versa, Carl Zeiss Inc.). 1601 projections were obtained for the specimen. The standard reconstruction algorithm is used to reconstruct sample. The voxel resolution at 350 nm with the narrower (ca. 350 μm x 350 μm) field of view was achieved.

该手术口罩样本经实验室型X射线微尺度CT扫描仪（蔡司Xradia 620 Versa，卡尔·蔡司有限公司）进行扫描。对于该样本，获得了1601个投影。采用标准重建算法对样本进行重建。实现了350纳米的体素分辨率，并具有较窄（约350微米×350微米）的视场。
