Abstract
Images of small plastic and food materials are obtained using a tomographic device based on image intensifier at optimum energy. The nux emitted by the X-ray tube is filtered using appropriate filters at the chosen optimum energy and reasonable monochromacy is achieved and the images are acceptably distinct. X-ray imaging is an established technique of detecting strongly attenuating materials as distinguished from weakly attenuating materials. The image contrast between the weakly attenuating materials can be enhanced by optimum selection of the energy and improving the spatial resolution. The image contrast between soft materials could be significantly enhanced by optimal selection of the energy of the X-rays using Monte Carlo methods. The images are analyzed using the profile data showing the internal defect of the object. It offers a new nondestructive method using the ionizing radiation techniques. With optimum value of energy and improving the spatial resolution the image contrast of the weakly attenuating materials can be improved considerably.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
