A NOVEL CT IMAGING SYSTEM WITH ADJACENT DOUBLE X-RAY SOURCES
Current computed tomography (CT) scanners rotate fast to reduce motion artifact. X-ray tube must work in a high power to make the image clear under short exposure time. However, the life span of such a tube may be shortened. In this paper, we propose a novel double sources CT imaging system, which puts two of the same X-ray sources closely with each other.The system is different from current dual ...

STUDY ON CONSTRUCTION OF A MEDICAL X-RAY DIRECT DIGITAL RADIOGRAPHY SYSTEM AND HYBRID PREPROCESSING METHODS
We construct a medical X-ray direct digital radiography (DDR) system based on a CCD (charge-coupled devices) camera. For the original images captured from X-ray exposure, computer first executes image flat-field correction and image gamma correction, and then carries out image contrast enhancement. A hybrid image contrast enhancement algorithm which is based on sharp frequency localization-contour...

MONTE CARLO SIMULATIONS OF A SCANNING SYSTEM BASED ON A PANORAMIC X-RAY TUBE WITH A CONICAL ANODE
Monte Carlo simulations were used to study photon production in a panoramic X-ray tube with a conical tungsten target to determine the optimal characteristics of the target shape and electron beam configuration. Several simulations were performed for accelerating potentials equal to 250 kV, 300 kV, and 500 kV with electron beams of various radii and anode sizes. The angular distribution of the pho...

PHOTONIC MATERIAL SELECTION OF SCINTILLATION CRYSTALS USING MONTE CARLO METHOD FOR X-RAY DETECTION IN INDUSTRIAL COMPUTED TOMOGRAPHY
Currently industrial X-CT system is designed according to characteristics of test objects, and test objects determine industrial X-CT system structure, X-ray detector/sensor property, scanning mode, and so forth. So there are no uniform standards for the geometry size of scintillation crystals of detector.Moreover, scintillation crystals are usually mixed with some highly toxic impurity elements, ...

X-RAY MAGNETIC DICHROISM IN THE COBALT-DOPED INDIUM TIN OXIDE FROM FIRST PRINCIPLE CALCULATIONS
The electronic structure of the Co-doped indium tin oxide (ITO) diluted magnetic semiconductors (DMSs) were investigated theoretically from first principles, using the fully relativistic Dirac linear muffin-tin orbital band structure method. The X-ray absorption spectra (XAS) and X-ray magnetic circular dichroism (XMCD) spectra at the Co ??3, In??2, Sn??2, andO?? edges were investigated theoretica...

SIMULTANEOUS REDUCTION IN NOISE AND CROSS-CONTAMINATION ARTIFACTS FOR DUAL-ENERGY X-RAY CT
Purpose. Dual-energy CT imaging tends to suffer from much lower signal-to-noise ratio than single-energy CT. In this paper, we propose an improved anticorrelated noise reduction (ACNR)method without causing cross-contamination artifacts. Methods. The proposed algorithm diffuses both basis material density images (e.g., water and iodine) at the same time using a novel correlated diffusion algorithm...
