ABSTRACT:
X-ray image degradation due to scattered radiation is reduced in a system using a planar sensor sheet by providing an X-ray absorbing sheet in front of the sensor sheet, or in back of the sensor sheet, or both. The thickness and material of construction of each X-ray absorbing sheet depends on the X-ray absorptivity of the material used, and whether the absorbing sheet is in front or in back of the sensor sheet. The front absorbing sheet is preferably as close as possible to the sensor sheet. The back absorbing sheet, if used, can be at essentially any distance from the sensor sheet, beyond a certain minimum, consistent with practical space limitations in the overall physical shape and design of the unit.
