Title
(EN) PULSED X-RAY IMAGING
(FR) IMAGERIE PAR RAYONS X PULSÉE
Abstract
(EN)
The X-ray imager combines a pulsed X-ray source with a time-sensitive X-ray detector to provide a measure of ballistic photons with a reduction of scattered photons. The imager can provide a comparable contrast-to-noise X-ray image using significantly less radiation exposure than conventional X-ray imagers, notably about half of the radiation.
(FR)
La présente invention concerne un imageur à rayons X qui combine une source de rayons X pulsée à un détecteur de rayons X sensible au temps pour fournir une mesure de photons balistiques avec une réduction de photons diffusés. L'imageur peut fournir une image à rayons X de contraste à bruit comparable utilisant une exposition au rayonnement significativement inférieure à celle des imageurs à rayons X classiques, avec notamment environ la moitié du rayonnement.
