The development of automatic analysis and classification methods for large databases of X-ray images is a pressing need that may have a great impact on clinical practice. To advance this objective the ImageCLEF-2015 clustering of body part X-ray images challenge was created. The aim of the challenge is to group digital X-ray images into five structural groups: head-neck, upper-limb, body, lower...

An Impulsive Heating Multiple Strand (IHMS) Model is able to reproduce the observational characteristics of EUV (∼ 1MK) active region loops. This model implies that some of the loops must reach temperatures where X-ray filters are sensitive (> 2.5MK) before they cool to EUV temperatures. Hence, some bright EUV loops must be preceded by bright X-ray loops. Previous analysis of X-ray and EUV acti...

ZnO nanostructure films were deposited by radio frequency (RF) magnetron sputtering on etched silicon (100) substrates using dry Ar/SF6 plasma, at two etching times of 5 min and 30 min, and on non etched silicon surface. Energy dispersive X-ray (EDX) technique was employed to investigate the elements contents for etched substrates as well as ZnO films, where it is found to be stoichiometric. Su...

Nano-zeolite CoAPO-5 as a member of AFI family, was synthesized via a hydrothermal treatment, and structurally characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), and energy dispersive X-ray analysis (EDAX). The effects of crystallization temperature and time on the structure of these powder products were studied. XRD patterns of the synthesized powders revealed a h...

An x-ray vision can be a unique method to monitor in real time and analyze the motion of mechanical parts which are invisible from outside. Our problem is to identify the pose, i.e. the position and orientation of an object from x-ray projection images. It is assumed here that the x-ray imaging conditions that include the relative coordinates of the x-ray source and the image plane are predeter...

Dental X-ray imaging helps dentists detect many problems such as caries, cysts and jaw structure problems. Clinical diagnosis preventive examinations of dental structures play an important role by providing a comprehensive evaluation with panoramic x-rays for dentists. However, researchers primarily use image processing methods to analyze improve increase its contribution the diagnostic time. I...
