We present a study that we have conducted to investigate whether the same visual-cognitive abilities are needed for 3D CT versus 2D multi-view screening of hold baggage.  \nIn the “Security in Practice” section, we are particularly pleased to introduce you to our new solution for testing and training X-ray screeners, the complete suite XRT4! It builds upon two decades of applied research and we provide insights into our scientifically based training and assessment, the strong technical features of our solution, and how we continuously improve it together with our customers.  \nAs always, we are looking forward to receiving any feedback you might have as well as your input on topics you would like us to address in upcoming newsletters.  \nWith best wishes for a nice summer.  \nDr. Diana Hardmeier Director  \nProf. Dr. Adrian Schwaninger Chairman  \nTOPICS IN THIS ISSUE:  \nRESEARCH PUT ACROSS  \nX-RAY SCREENING OF HOLD BAGGAGE: WHAT VISUALCOGNITIVE ABILITIES ARE NEEDED FOR 2D AND 3D IMAGING?  \nThe task of an airport security officer is to visually inspect X-ray images of luggage and take a decision within seconds whether it is a harmful piece of baggage or not. While still many airports conduct security screening with 2D multi-view X-ray imaging technology, newer technology is based on 3D CT imaging and brings along new features such as 360° rotation and slicing through the bag. Important to know is: “Are the same visual-cognitive abilities needed for 3D CT image inspections?” This article describes results from a first study and what these results imply for future personnel selection.  \nSECURITY IN PRACTICE  \nX-RAYTUTOR 4 (XRT4): BUILT UPONTWO DECADES OF APPLIED RESEARCH  \nThrough continuous improvement, research and strong connections to partners and customers, CASRA presents the new testing and training solution XRT4! The computer-based training, which supports screeners through all the employment phases, incorporates the scientifically proven individually adaptive training algorithm. XRT4 allows to train with single-view, dual-view and 3D CT modules, while adapting the user interface to most common vendors. XRT4 Expert gives even the opportunity to create individual and personalized modules for training and testing. This article explains how the solution has evolved and how the results have been implemented into XRT4 .  \nSCIENCE& SECURITY Issue 23  \nRESEARCH PUT ACROSS  \nX-RAY SCREENING OF HOLD BAGGAGE: WHAT VISUAL-COGNITIVE ABILITIES ARE NEEDED FOR 2D AND 3D IMAGING?  \nText: Sarah Merks  \nUp to this day, security screening of hold baggage at many airports is still being conducted with 2D multiview X-ray imaging technology. Newer technology is based on 3DCT imaging. Such systems offer the possibility to rotate a bag around 360 degrees, slice through a luggage and they provide state-of-the-art explosives detection systems (EDS) . With the transition from 2D multi-view to advanced CT imaging, the question arises whether airport security officers (screeners) need the same visual-cognitive abilities when visually inspecting CT images of hold baggage. This article describes results from a first study and what these results imply for future personnel selection.  \nThe task of airport security officers (screeners) is to visually inspect X-ray images of luggage, which consists of visual search and decision making [1– 4] . In cabin baggage screening (CBS), prohibited items are guns, knives, improvised explosive devices (IEDs) and other items such as","cbCaimDvMqqraooV","https://ap.wps.com/l/cbCaimDvMqqraooV","pdf",2762510,11,"English","# Research Put Across\n## X-Ray Screening of Hold Baggage: What Visual-Cognitive Abilities Are Needed for 2D and 3D Imaging?\n# Security in Practice\n## X-RayTUTOR 4 (XRT4): Built Up on Two Decades of Applied Research","[{\"question\":\"What is the main research question in Issue 23’s “Research Put Across” section?\",\"answer\":\"Whether airport security screeners need the same visual-cognitive abilities when inspecting 3D CT images compared with 2D multi-view screening for hold baggage.\"},{\"question\":\"What additional capabilities does 3D CT imaging bring versus 2D multi-view imaging?\",\"answer\":\"3D CT adds features such as 360° rotation of passenger baggage and slicing through the bag, along with related image processing functions.\"},{\"question\":\"What does XRT4 provide in the “Security in Practice” section?\",\"answer\":\"XRT4 is a computer-based testing and training solution for X-ray screeners using scientifically proven individually adaptive training, supporting single-view, dual-view, and 3D CT modules.\"}]","Science & Security - Issue 23 - Summer Newsletter | PDF",1790429439,28]
