2014年1月16日 · The Department of Homeland Security (DHS), U.S. Customs and Border Protection (CBP) uses Non-Intrusive Inspection (NII) technologies to conduct inspections of cargo and conveyances for contraband as part of its mission to stop illicit imports to facilitate lawful travel and trade.

VACIS ® MLX is the newest solution in the VACIS product line and features the shortest wheelbase and the lightest weight in its class. This new high-energy X-ray system combines versatile mobility with technology that is proven through hundreds of VACIS system deployments.

Non-Intrusive Inspection (NII) technology enables CBP to detect contraband (e.g., narcotics and weapons) and materials that pose potential nuclear and radiological threats. Technologies deployed to our Nation’s land, sea, and air ports of entry include large-scale X-ray and Gamma-ray imaging systems, as well as a variety of porta -

2018年11月23日 · One of the main tasks of the TEG-NII is to promote synergies between the Customs and the Industry to develop a standard NII data format with the purpose to facilitate interoperability of different NII equipment provided by different manufacturers/vendors; to facilitate exchange of images in a unified file format within and between Customs admini...

CBP Officers use NII systems to help them effectively and efficiently detect and prevent contraband, including drugs, unreported currency, guns, ammunition, and other illegal merchandise, as well as inadmissible persons, from being smuggled into the United States, while having a minimal impact on the flow of legitimate travel and commerce.

2023年4月14日 · ADA solutions will provide computer-assisted analysis of NII images and other data that will allow for an increase in the thoroughness of inspections, reduce the time needed to conduct review of low-risk trade and travel, and support the analysis of complex inspections by CBP officers while minimizing human labor demands.

单独的.nii格式文件的优势就是可以用标准的压缩软件（如gzip），而且一些分析软件包（比如FSL）可以直接读取和写入压缩的.nii文件（扩展名为.nii.gz）。 由于NIFTI格式逐步取代了Analyze格式的关系，因此NIfTI格式也可使用独立的图像文件（.img）和头文件（.hdr）。 使用ITK-snap软件读取： 使用方法可以参阅： 代码读取： 来源于 (LUNA2016)，每个病人数据包含： 以深度学习研究医学影像已成为医学图像分析研究热点。 一、DICOM数据格式简单的说，一 …

2022年10月5日 · 因此记录下学习nii,png与np.array之间格式转换的学习及踩坑过程，以itk-snap勾画的mask为例，原始保存为nii格式。 import radiomics. import SimpleITK as sitk. import matplotlib.pyplot as plt. import glob . （一）将nii转换为png格式，若批量加for循环即好. plt.imsave('C:\\Users\\Administrator\\Desktop\\img\\mask_{:0>3d}.png'.format(n),im,cmap='gray') # {:0>3d}字符串格式化右对齐3位，用0补齐.

2024年12月2日 · 总的来说，"图像分割标签+nii格式的预处理"涵盖了医学图像分析的重要步骤，包括使用ITK-snap进行图像标注，将nii转换为npy以适应模型训练，以及在必要时进行nii与PNG之间的格式转换。

2022年10月19日 · 以下是使用3D Slicer将DICOM数据转换为NIfTI格式的步骤： 打开3D Slicer。 在菜单栏中选择"Modules" → “DICOM”。 在DICOM模块中，点击"Import"按钮，然后选择你的DICOM数据的文件夹。 导入完成后，你的DICOM数据将出现在DICOM浏览器中。 选择你想要转换的数据，然后点击"Load"按钮。 现在，你的DICOM数据已经加载到3D Slicer中。 在菜单栏中选择"Modules" → “Save”。 在保存对话框中，选择你想要保存的图像和路径，然后在"File …
