SCANNING IMAGING SYSTEM, APPARATUS AND METHOD

摘要

One or more embodiments of the present invention provide a scanning system for imaging one or more objects, comprising: an imaging element; a conveyor for providing relative movement between an object to be scanned and said imaging element; said imaging element comprising a high-energy radiation emitter and a high-energy radiation detector spaced from the high-energy radiation emitter to allow passage of the object to be scanned between the high-energy radiation emitter and radiation detector, and the high-energy radiation detector operative to receive radiation emitted from said high- energy radiation emitter and incident on said object; wherein said high-energy radiation detector comprises two or more detection elements disposed in a direction of relative motion of the object to be scanned and said imaging element, with each detection element operative to detect high-energy radiation received at the high-energy radiation detector in a particular energy range. One or more embodiments of the present invention also provide a scanning device and method.
