Abstract:
Introduction. X-ray methods are currently widely used in manufacturing of various products and components of the electronics industry, including micro- and nano-electronics. One of the most informative and illustrative methods is projection X-ray microscopy. Specialized X-ray systems for process control are developed and used in industry. The key element in the design of an X-ray inspection system is an X-ray tube. In the overwhelming majority of cases, X-ray inspection systems are based on collapsible microfocus x-ray tubes with constant pumping. This greatly complicates the design of the ins

Abstract:
An experimental implementation of the “in-line” method of X-ray phase contrast using a standard wide-focus X-ray tube as a polychromatic source is described. Using the proposed experimental scheme, in vitro tomographic measurements of a sample of human brain pineal gland are carried out, and the morphological structure of the soft tissues of this organ is visualized based on the results obtained. The advantage of phase-contrast tomography in comparison with traditional absorption tomography for studying the structural features of soft tissues is experimentally demonstrated. The “in-line” phase

Abstract:
The effects of microsize and nanosize particles in composite structures as well as the incident radiation energy on X-ray attenuation is the focus of this study. To examine these effects, composite samples with different particle sizes of Al2O3 and with different thicknesses were prepared. Characteristic X-rays are applied as monochromatic X-rays and measurements were performed using an X-ray tube with a secondary excitation source instead of radioisotopes. In order to improve the efficiency and minimize the background effects a special detection system was designed and prepared. The linear at

This work was carried out to obtain sound welds and to select the most suitable binary metal joint among three different dissimilar metal combinations such as Zr-4/Ta, Mo/Ta and Ti/Ta (seal tube/sensor sheath) joints for an instrumented nuclear fuel irradiation test. To do this, the Taguchi experimental method was employed to optimize the experimental data. In addition, metallography, micro-focus x-ray radiography and a hardness test were conducted to examine the welds. From the weld bead appearance, penetration depth and bead width as well as the weld defects standpoint, the Zr-4/Ta joint is

Abstract:
A high-resolution in vivo micro-CT system for combining with fluorescence molecular tomography (FMT), was constructed and applied in small animal imaging. The fast scanning micro-CT system designed to provide high-resolution anatomic information and reconstruction priors, consisted of a flat panel detector (FPD) based on amorphous silicon (a-Si) and a micro-focus x-ray tube. The Feldkamp algorithm was adopted in image reconstruction with graphic processing unit (GPU). The system spatial resolution of 13 lp/mm was achieved when the diameter of image field was 6 cm with the system magnification

Abstract:
The in-line phase-contrast imaging has great potential for clinical imaging applications. This work presents a general theoretical formalism for the in-line phase-contrast imaging. The theoretical formalism developed in this work is derived by taking a new strategy to calculate the Fourier transform of image intensity directly. Different from the transport of intensity equation (TIE) formalism for phase-contrast imaging in literature [6], this general formalism covers both the near field regime and the holography regime of phase-contrast imaging. The image intensity formulas have been derived

Abstract:
Abstract Multiple energy bin spectral micro-CT (SμCT) is an advanced imaging technique that allows multi-material decomposition according to their specific absorption patterns at a sub-100 μm scale. Typically, iodine is the preferred CT contrast agent for cardiovascular imaging, while gold nanoparticles have gained attention in recent years owing to their high absorption properties, biocompatibility and ability to target tumors. In this work, we demonstrate the potential for multi-material decomposition through SμCT imaging of a test sample at the PEPI lab of INFN Trieste. The sample, consisti

With the recent improvements in the brightness of laboratory X-ray sources, high-quality data can be collected from a wider range of crystal samples on in-house diffractometers. To cope with the resulting increase in workload it is important to be able to collect highest-quality data as quickly and efficiently as possible. Agilent Technologies develop and supply X-ray systems for small-molecule and macromolecular crystallography, which include SuperNova line of diffractometers utilizing the latest generation sealed-tube micro-focus X-ray sources, as well as the new range of Atlas S2, Eos S2 an

Abstract:
In recent years, X-ray computed tomography (XCT) has successfully entered the field of dimensional metrology. XCT offers advantages over traditional tactile and optical coordinate measuring machines because of its ability to detect both the outer and inner geometries of an object. Due to the complex nature of XCT, there are a large number of factors which can influence dimensional measurement; many of these factors are still poorly understood. The novel study of a number of influence factors associated with the X-ray tube and their influence on dimensional measurement in micro-focus cone-beam
