Abstract
One or more systems and/or techniques are disclosed herein for determining the orientation of a focal spot of a radiation source based upon shadows that are imposed on channels of a detector array from an anti-scatter grid. The anti-scatter grid is comprised of one or more anti-scatter plates that are focused on a point other than an intended focal spot of the radiation source. Such anti-scatters plates cast shadows on the detector array (even when the focal spot is located at the intended focal spot). By measuring changes in the signals generated by channels of the detector array that detect the shadows, it may be determined how the orientation of the focal spot has changed throughout an examination or between a calibration scan and an examination scan, for example.
