A study was made of the relation between image contrast and image size of x-ray image quality indicators (IQIs) of the hole and wire types. The normal contrast was reduced by superimposing 'scattered' radiation. The resulting image contrat was calculated by multiplying the normal contrast by ...
A method for the analysis of bone mineral density and/or bone structure from x-ray images using calibration phantoms which act as references in order to determine bone structure from an x-ray image. Regions of anatomical interest (ROI) in the image are identified. The method comprises: obtaini...

In underdoped cuprates, the interplay of the pseudogap, superconductivity, and charge and spin ordering can give rise to exotic quantum states, including the pair density wave (PDW), in which the superconducting (SC) order parameter is oscillatory in spa
The shell integrity is measured by imaging the core emission at different x-ray energies. Time-integrated images of the titanium-doped targets have been obtained using a pinhole array with filters below and above theK-edge energy of titanium and recorded on DEF film. The optical depth ratio ...
This has led to the development of impedance imaging as a supplementary or alternative method to X-ray mammography for screening and assessment of breast cancers. However low spatial resolution and poor signal to noise ratio has limited the clinical application. Methods In order to improve spatial ...
The surface chemical structure and energy state of 3DIO LaCoO3-x and conventional LaCoO3 nanoparticle (NP–LaCoO3) perovskites are investigated by using angle-resolved X-ray photoelectron spectroscopy (ARXPS), Ultraviolet photoelectron spectroscopy (UPS), and inverse photoemission spectroscopy (IPES), ...
Charge density wave (CDW), the periodic modulation of the electronic charge density, will open a gap on the Fermi surface that commonly leads to decreased or vanishing conductivity. On the other hand superconductivity, a commonly believed competing order
The lower-energy emission spectra that we observed in these binaries is distinct from the higher-energy spectra associated with the population of accreting white dwarfs that dominates the central eight parsecs of the Galaxy6. The properties of these X-ray binaries, in particular their spatial ...
