X-ray inspection systems are a standard feature in many ports. These X-ray systems have the unique ability to non-destructively image the contents of entire cargo containers in just a few seconds. It is a difficult task, however, to identify what is in the container based on the obtained X-ray images. The superposition of two images with different contrasts – like in dual-energy X-ray imaging – can enhance the effectiveness of the detection. A novel X-ray imaging technology now introduces an entirely new type of contrast based on movement. This technology can be combined with existing single-energy and dual-energy X-ray imaging methods, opening new possibilities in port security applications.

One important application of the dynamic imaging technology could be finding stowaway pests in the cargo. Stowaway pests travel hidden within transported goods and may damage the cargo while being shipped. In addition to this, potentially invasive species often travel as stowaway pests and arrive to new territories unnoticed. Although better part of these exotics are harmless, approximately 20 to 30 percent of the introduced species are pests and cause major environmental and economic problems. Read the full article here!
