Test and Evaluation Plan for Threat Image Projection with the CTX 5000 Explosives Detection System [open pdf - 2MB]
"The effectiveness of Threat Image Projection (TIP) as an element of the Screener Proficiency Evaluation and Reporting System (SPEARS) for checked baggage screening with the CTX 5000 is evaluated. The CTX 5000 combines computed tomographic imaging and automated detection of explosives. This complex system requires that screeners learn to skillfully discriminate innocent bags that cause the system to alarm from genuine threats. Testing is designed to determine the effectiveness of TIP in meeting the critical operational issues described in this plan. Specifically, is TIP effective in improving and maintaining screener performance in the detection of improvised explosive devices? Can the performance of individual screeners be monitored effectively with TIP? The testing will be conducted at airports where the CTX 5000 system is currently located."
