Abstract
The present invention, in one form, is a system which, in one embodiment, determines an x-ray beam z-axis profile and properly positions a detector array. Specifically, in one embodiment, signals intensities from the detector array are used to determine the optimal position of the detector array. In addition, the signal intensities are utilized to adjust an aperture of a pre-patient collimator. By adjusting the collimator aperture an x-ray beam umbra is aligned with the edges of the detector array. As a result, an optimal x-ray beam is radiated toward the detector array.
