Two thermal methods to measure the energy fluence of a brief exposure of diagnostic x rays
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
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.
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 ...

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 ...
