Comparative analysis of human and bovine teeth: Radiographic density
(2008-12-01)
Since bovine teeth have been used as substitutes for human teeth in in vitro dental studies, the aim of this study was to compare the radiographic density of bovine teeth with that of human teeth to evaluate their usability ...

Two thermal methods to measure the energy fluence of a brief exposure of diagnostic x rays
(1992-07-03)
This paper describes two simple thermal methods for measuring the energy fluence in J/cm 2 from a diagnostic x-ray exposure. Both detectors absorb essentially 100% of the radiation and give a signal that is directly ...

Diffusion-reaction studies in low permeability shale using X-ray radiography with cesium
(Elsevier, 2013-12)
An X-ray radiography method for the determination of diffusion coefficients in rock has been modified to provide an estimation of diffusion-reaction parameters for the sorbing tracer, cesium (Cs+ ). Cesium tracer diffusion ...
A survey of radiographic measurement estimation in assessment of dental implant length.
(2007-11-14)
The aim of this study is to survey radiographic measurement estimation in the assessment of dental implant length according to dentists' confidence. A 19-point questionnaire with closed-ended questions was used by two ...

(British Inst Radiology, 2003-11-01)
Objectives: To survey the current radiographic prescriptions in dental implant assessment amongst dentists in Brazil.Methods: Sixty-nine dentists were interviewed during a dental implant meeting by two calibrated graduate ...
Multiple imaging radiography at LNLS
(ELSEVIER SCIENCE BVAMSTERDAM, 2008)
An analyzer-based X-ray phase-contrast imaging (ABI) setup has been mounted at the Brazilian Synchrotron Light Laboratory (LNLS) for multiple imaging radiography (MIR) purposes. The algorithm employed for treating the MIR ...
Plasma focus based flash hard X-ray source in the 100 keV region with reproducible spectrum
(Elsevier Science, 2010-10)
A pulsed hard X-ray source with shot to shot reproducible spectrum, based on a 4.7 kJ small-chamber Mather-type plasma focus device, is presented. The hard X-ray output spectrum was measured in a single shot basis by ...
