Computed radiography

Biomedicine & Pharmacotherapy, 1998
In several medical centers computed radiography has almost completely replaced the use of conventional screen-film systems for general radiography. The aim of this paper is to explain the basic principles of the four most frequently numerical detectors used in the world, with emphasis on the phosphor plates, which are the most frequently used both in ...

Overcoming breath-hold difficulties with GRASP VIBE for contrast-enhanced MRI liver and pancreas to improve image diagnostic quality

BMJ Open Quality
Contrast-enhanced MRI is essential for the evaluation and characterisation of indeterminate liver and pancreatic lesions. Conventional volumetric 3D T1-weighted sequences, such as the volumetric interpolated breath-hold examination (VIBE), play a key ...

Statistical Uncertainty in Quantitative Neutron Radiography

, 2017
We demonstrate a novel procedure to calibrate neutron detection systems commonly used in standard neutron radiography. This calibration allows determining the uncertainties due to Poisson-like neutron counting statistics for each individual pixel of a ...

Sensitivity on Earth Core and Mantle densities using Atmospheric Neutrinos [PDF]

, 2009
Neutrino radiography may provide an alternative tool to study the very deep structures of the Earth. Though these measurements are unable to resolve the fine density layer features, nevertheless the information which can be obtained are independent and ...
