Grid-like contrast enhancement for bedside chest radiographs acquired without anti-scatter grid
Bernd Menser, PhD, X-Ray Scientist Bedside chest radiographs can be acquired with or without an anti-scatter grid. Using a grid may improve image contrast, although it is frequently avoided in clinical practice, due to dose considerations, beam alignment difficulties, and a more complicated workflow[2]. Also, structures appearing from the (usually stationary) grid may interfere with diagnostic ...
متن کاملComparative scatter and dose performance of slot-scan and full-field digital chest radiography systems.
PURPOSE To evaluate the scatter, dose, and effective detective quantum efficiency (DQE) performance of a slot-scan digital chest radiography system compared with that of a full-field digital radiography system. MATERIALS AND METHODS Scatter fraction of a slot-scan system was measured for an anthropomorphic and a geometric phantom by using a posterior beam-stop technique at 117 and 140 kVp. Me...
متن کاملSimulation and patient studies of scatter correction in cardiac SPECT imaging
Introduction: Myocardial perfusion imaging is a nuclear medicine imaging method that is used to detect coronary artery diseases. One of the main sources of error in this imaging method is the detection of Compton scattered photons in the photopeak energy window used for data acquisition. This results in the degradation of the image contrast, and therefore decreases the...
متن کاملScatter reduction for grid-less mammography using the convolution- based image post-processing technique
X-ray Mammography examinations are highly affected by scattered radiation, as it degrades the quality of the image and complicates the diagnosis process. Anti-scatter grids are currently used in planar mammography examinations as the standard physical scattering reduction technique. This method has been found to be inefficient, as it increases the dose delivered to the patient, does not remove ...
متن کاملRefinement of Imaging Processing of Scatter Correction and Beam Hardening Tools for Industrial Radiography and Cone Beam CT
Digital detector arrays are used for industrial radiography and cone beam CT. Scattering and beam hardening artifacts reduce the achievable contrast sensitivity and can severely limit the size of the part to be scanned or require large amounts of shielding to block scatter outside the inspection area of interest. Varian’s image processing toolkit contains a set of dll’s that can easily be deplo...
