Abstract
A radiography marker for indicating the inclination angle of a radiography imaging receiver has a portion defining at least one area transparent to x-radiation and an angle indicator element attached to the portion defining at least one area at a pivot point and manually adjustable along the portion defining at least one area to set any of a plurality of angular positions over at least a portion of the at least one area transparent to x-radiation. At least a portion of the indicator element is opaque to x-radiation.
