  • Dispersion of Rhizophora spp wood phantom in diagnostic X-rays

    This paper focuses on the study of dispersion properties of Rhizophora spp. (mangrove) wood phantom when exposed to X-rays. The main objective of the dispersion study was to identify the highest dispersion direction. Four pieces of Rhizophora Spp. wood phantom of the same size but different thickness were tested in this study. The dispersion of the phantom was traced by using thermal luminescence dosimetry (TLD). As much as 8 TLDs were used in each phantom. These TLDs were numbered as TLD 1 to 8 and were placed surrounding the phantom in counter clockwise arrangement. The setup of experimental apparatus was kept the same for every repeated experiment. The focal length was kept at 100cm, current used was 100 mA at exposure time 0.20 seconds and exposure area (field size) of 138 ×132 mm<sup>2</sup>. When the kilovoltage peak (kVp) value was varied, the other parameter value was fixed. Results showed that the dispersion from Rhizophora spp. wood phantom was at the back (TLD position was 3 ± 4 %). The dispersion of Rhizophora spp. wood phantom increased when all the parameters increased except for enhanced focal length. The outcome of this study indicates that the Rhizophora spp. wood phantom is an alternative tool to use as a phantom for diagnostic study as it has tissue equivalent features. The dispersion of Rhizophora spp. wood phantom was also found lower in high photon energy (kVp high), suggesting that it can produce optimum dose if applied to body tissues. Further development is to vary the other parameters (focal length, current, exposure time, and field size) to proof it is suitable as a phantom to use in diagnostic study if applied to body tissue.

  • Dose reduction options by monochromatic X-rays

    Dose reduction in X-ray based medical diagnostics is essentially important in screening applications such as mammography where a large number of potentially healthy people are exposed to ionizing radiation. Several novel concepts of compact X-ray sources with a very narrow (quasimonochromatic) spectral bandwidth are under development, and their use in diagnostic systems of the future may have strong impact on the patient dose. The study presented here is based on simulations and predicts a significant dose reduction achievable in a mammography-Iike scenario.

  • Development of Control Strategy for Power Supply to Optimize Thermals Effects Induced in X-rays Tube for Medical use

    through this study, an approach has been developed to achieve a power transfer control strategy for supplying an X-rays tube belonging to the field of medical imaging. And those, under ideal conditions, through the stages of conversion of electrical energy, whose qualities of each stage behavior, have been effectively selected and simultaneously arranged. So, in addition, concerns about the size, the volume and the weight of these assemblies, the thermal stresses persist strongly in the fragility of the X-rays generators. To develop the optimization of thermal accumulations, a contribution hybrid controller is tested to overcome these disadvantages. The successive radiological outlets tend to increase the thermal effects, despite the fact that the time and the cooling system, which remain insufficient, lead to a longer and more cost-effective life of these expensive equipment. Instructively, the prescription of any booting supply must be included in the standardized load range, in accordance with the time constants and depreciation developed by the system. However, the results obtained confirm this load selection state, including the performance and response qualities of the system in the vicinity of the conditions previously dictated by the specifications of this load of this type of power supply.

  • The impact of diffraction enhanced imaging with different X-rays energies

    To discuss the relation between the visibility of X-ray diffraction enhanced imaging (DEI) and X-rays energy, DEI imaging of liver tissue was studied using the hard X-rays from 4W1A beam line at the Beijing Synchrotron Radiation Facility (BSRF). The peak-position image, which is recorded at the peak of the rocking curve, has higher visibility. The visibility of the peak-position image or apparent absorption image keeps unchanged when different X-ray energies are used. The visibility of refraction image tends to be weakened when the X-ray energy is increased. As a result, the visibility of peak image or apparent absorption image is better when using 15 keV X-rays, but the visibility of refraction image is best when using 10 keV X-rays.

  • Study of the combined effects of X-rays and low-energy microwave electromagnetic field on the state of chromatin in the nuclei of human buccal epithelium cells

    Isolated human buccal epithelium cells of two men (22 and 25 years) and women (15 years) were irradiated with X-rays (200 and 800 μRh/h) for 1 minute, and microwaves (frequency - 36.6 GHz, the power density at the object level - 100 μW/cm2) during 1 min. X-rays were used before and after microwave irradiation, with interval in 20 min. The number of granules of heterochromatin was determined after orcein staining immediately after irradiation. It was shown that the response of cells to radiation differs in some way for cells of different donors. Common features in the reaction of cells - the number of heterochromatin granules after irradiation at 200 μRh/h was significantly higher than after irradiation intensity of 800 μRh/h. Microwave irradiation before and after X-ray treatment virtually eliminates these differences.

  • A magnetically insulated transmission line connected to the ASTERIX 6MV generator for X-rays diode research

    Summary form only given. At the "Polygone d'Experimentations de Moronvilliers" (PEM near Reims), the CEA/DAM develops a new 8 MV-50 Omega Flash (50 ns) X-rays facility for radiographic studies. This pulsed power machine is based on a linear transformer driver (LTD) generator who provides the energy to an X-rays diode. The geometry of the diode is not chosen yet, however the previous experimental tests show encouraging results from a negative rod pinch scheme. The ASTERIX generator is a Blumlein system connected to a vacuum chamber via an axial insulator stack. After, the energy transmits through a short (1 meter) coaxial line with impedance of 115 Omega and reaches the diode region. This generator has a maximum voltage of 7.2 MV on a 72 Omega load. It was used since 2000 to perform X-rays diode research using the described geometry. To go further on the diode investigation and optimization, a MITL section has been designed and connected to the ASTERIX generator. This 2 meters line replaces the vacuum chamber right after the insulator stack. The sizes of the internal and external conductors were chosen to match the future LTD machine. The impedance, with electron flowing in the vacuum gap is 50 Omega. We propose to present the results obtained with this new configuration. First, a simple "large surface plane diode" was used to control the overall functioning. A specific diagnostic was developed to measure the current flow at different radius using a multi inductive gaps system. After those tests, a RPN geometry will be tested. If so the results will be added to the presentation proposed

  • Investigation on the pseudospark electron beam and its application for the generation of soft X-rays

    An investigation on the pseudospark electron beam is presented in this paper. Time-integrated and time-resolved pictures of the X-rays generated by the electron beam are taken with a special X-ray pinhole camera. They show the spatial and temporal development of the pseudospark electron beam. Time- integrated pictures indicate spatial instabilities of the electron beam caused by a bent or broadened electron beam due to space charge effects. The results of the time-resolved measurements show X-ray emission only during two short periods at the very beginning of the discharge before the beam current reaches its maximum. Only during these periods does the electron beam contain high- energy electrons. In between these two periods the energy of the beam electrons decreases because of a space-charge-limited beam transport.<<ETX>>

  • Food irradiation technology using electron beams and x-rays

    In this presentation we will discuss the technology of food irradiation using electron accelerators. Food irradiation has generally come to describe the use of ionizing radiation (e.g., energetic electrons and x-rays) to decrease the population of, or prevent the growth of, undesirable biological organisms in food. The many beneficial applications include for example, the disinfestation of insects in fruits and grains, the inhibition of sprouting in potatoes and onions, the delayed ripening of fresh fruits and vegetables, and the enhanced safety and sterilization of fresh and frozen meat products, seafood, and eggs. With special regard to food safety, bacteria such as Salmonella enteridis, Listeria monocytogenes, Campylobacter jejuni and Escherichia coli serotype O157:H7 are the primary causes of food poisoning in industrialized countries. In 1999, food-borne illnesses were responsible for an estimated 5000 deaths in the USA alone. Ionizing doses in the range of only 1-5 kilogray (kGy) can virtually eliminate these organisms from food, without affecting the food's sensory and nutritional qualities, and without inducing radioactivity. Recognizing this fact, members of the World Health Organization's Food Safety Unit have described food irradiation as possibly the most significant contribution to public health to be made by food science and technology since the pasteurization of milk.

  • Frontiers in extreme nonlinear optics: Attosecond-to-zeptosecond coherent kiloelectronvolt X-rays on a tabletop

    Summary form only given. The past three years in a row marked the 50th anniversaries of three significant innovations in optics: the invention of the laser; the discovery of the nonlinear upconversion of laser light in a spectral region where laser light has not been available; and the outlining of phase matching of this upconversion process - a recipe that makes the newly generated laser-like light bright and usable for applications. The same revolution that made it possible to create well directed beams in the visible region of the spectrum is only now happening for X-rays. Large-scale X-ray free electron lasers are promising to capture images of ultrafast dynamics in a single shot. An extreme version of nonlinear optics - high harmonic generation (HHG) - can also generate bright, coherent, beams of X-rays, with very short wavelengths <;7.7 angstroms, in a tabletop-scale setup for the first time [1]. This practically realizes a coherent version of the Roentgen X-ray tube in the soft X-ray region. Improved understanding of the microscopic quantum physics and macroscopic nonlinear optics of high harmonic generation [2-5], as well as the development of novel ultrafast mid-IR lasers [6] have lead to this rapid progress in the past few years, essentially solving the phase matching problem of HHG in the X-ray region. In addition, these kiloelectronvolt HHG X-rays have a supercontinuum structure with the broadest coherent bandwidth (>1.3 keV) that any light source, large or small scale, can generate to date. Such an ultrabroad spectral bandwidth can support X-ray pulses as short as 2.5 attoseconds and is scalable towards zeptosecond pulse durations. These unique, ultrafast, laser-like X-ray beams promise revolutionary new capabilities for understanding and controlling how the nanoworld works on its fundamental time and length scales. This understanding is relevant to the next generation data and energy storage devices, nano- electronics, bioimaging, and future medical diagnostics.
