Title:
MULTISPECTRAL STATIC CT DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/096770
Kind Code:
A1
Abstract:
A multispectral static CT device comprising a multipoint distributed ray generating device (31), multiple rows of sensors (B, C, E, and F), a data collecting device (34), a luggage conveying and control device (32), and a multi-energy projection data processing device (35). Combination of a static CT scan mode with a multispectral analysis technique not only retains existing advantages of static CT, such as fast scan speed, simple mechanical structure, and conserved costs for slip rings and detectors, but also implements identification of material compositions, thus providing a high practical value in scenarios of security inspection and customs anti-smuggling.
