conclusions because this incident may have occurred during the patient’s neonatal period, it may be a case of child abuse. in spite of the very limited number of cases in the literature, having a stepmother, a stepfather, or a babysitter, being the youngest child, or having family members who suffer from psychiatric disorders, (especially if these relatives are responsible for child care), livi...
A flexible microdome-grooved Gd(2)O(2)S:Tb scintillator is simulated, fabricated, and characterized for digital radiography applications. According to Monte Carlo simulation results, the dome-grooved structure has a high spatial resolution, which is verified by X-ray image performance of the scintillator. The proposed scintillator has lower X-ray sensitivity than a nonstructured scintillator bu...
Background and purpose: Increasing number of patients undergoing x-ray examinations has created a global concern due to the deleterious biological effects associated with x-ray exposure. Adherence to ionizing radiation protection principles could be of great benefit in decreasing these effects. Accordingly, the aim of this study was to survey radiation protection in diagnostic x-ray imaging in ...
Flat-panel X-ray image detectors have been shown to be suitable to replace the conventional X-ray filmjscreen cassettes for medical radiography (static or snapshot imaging). They are capable of capturing the X-ray image digitally immediately after the X-ray exposure which permits a convenient clinical transition to digital radiography. There are two general approaches to the flat-panel X-ray de...
The present paper describes laboratory tests on steady granular flows down a smooth chute using X-ray radiography. By an original set-up with gate at its end, standing discontinuites in height, velocity and density, namely jumps, were produced during the flows. radiography was successful to get consistent measurements of free-surface density profiles along under different flow states: (nearly) ...
