The events of 9/11 have demonstrated the increased need to detect terrorists and their threats. The threats include nuclear, biological and explosives targeted at infrastructure and transportation. The threats may be delivered in cargo, in luggage and by suicide bombers. Many different types of equipment have been deployed to detect these threats. The topics of this presentation include reviews of the threats and the detection technologies, and a discussion of the issues related to the deployment of these technologies. The talk will emphasize technologies that have been derived from medical imaging for detecting explosives targeted at aviation security.


Carl Crawford is president of Csuptwo, LLC, a technology development and consulting company in the fields of medical imaging and explosive detection for Homeland Security. He has been a technical innovator in the fields of computerized imaging for more than thirty years.  His technology has resulted in 89 U.S. Patents and approximately $1.5 billion of revenues for his clients. Dr. Crawford was the Technical Vice President of Corporate Imaging Systems at Analogic Corporation, Peabody, Massachusetts, where he led the application of signal and image processing techniques for medical and security scanners.  He developed the reconstruction and explosive detection algorithms for a computerized tomographic (CT) scanner deployed in airports worldwide.  He was also employed at General Electric Medical Systems, Milwaukee, Wisconsin, where he invented the enabling technology for helical scanning for medical CT scanners, and at Elscint, Haifa, Israel, where he developed technology for cardiac CT scanners. He also has developed technology for magnetic resonance imaging (MRI), single photon emission tomography (SPECT), positron emission tomography (PET), ultrasound imaging (U/S), dual energy imaging and automated threat detection algorithms. Dr. Crawford has a PHD in electrical engineering from Purdue University. He is a Fellow of the IEEE, a Fellow of the American Association of Physicists in Medicine (AAPM), and is an associate editor of IEEE Transactions on Medical Imaging.
