Abstract
Systems and methods are provided for scanning an item utilizing an X-ray scanner in order to facilitate a determination of whether the X-ray radiation penetrated through the entirety of the scanned item. Various embodiments comprise a conveying mechanism, an X-ray emitter, a detector, and an X-ray penetration grid (XPG). The XPG may comprise a radiopaque grid that may serve as a reference for determining whether radiation passes through the scanned item, the grid oriented such that the grid members are neither parallel nor perpendicular to the direction of travel. Such orientation may minimize or eliminate “ghosted” radiation signals included in a visual display of the radiation received by the detector. A scanned item may be oriented with the XPG such that radiation emitted by the X-ray emitter that passes through a portion of the scanned item must also pass through the XPG before being received by the detector.
