This project investigates the development of automated explosives detection and classification algorithms for increased throughput by using combinations of sensors in an active, adaptive testing scheme. Multi-modal sensors can help find and distinguish the features of existing threats, and even discover and classify new ones. The significance of this project lies in the potential to use multipl...
Imaging with visible light today uses numerous contrast mechanisms, including bright- and dark-field contrast, phase-contrast schemes and confocal and fluorescence-based methods. X-ray imaging, on the other hand, has only recently seen the development of an analogous variety of contrast modalities. Although X-ray phase-contrast imaging could successfully be implemented at a relatively early sta...
Neutrons and X-rays provide a means to peer into the interior of objects, which are otherwise not optically visible. With the development of detector technology and new radiation sources, several new imaging technologies using x-rays and neutrons have emerged and have found widespread applications in industry, material science and medical imaging. The last two decades have seen the development ...
Objective(S): The dangerous effects of X-ray have been elucidated by scientific studies in occupational health hygiene. X-ray protective like an apron, thyroid shield and gloves have been made of lead (Pb) to protect against X-ray. However, such equipment makes a lot of safety and health problems such as toxicity, weight, inflexibility and troubles usage in a physician. To ove...
