摘要： Systems, methods and apparatus are provided through which, in some embodiments, an electronic sensor is positioned in the field of projection of an X-ray source, and the electronic sensor measures the deviation between a visible light field and an X-ray field. In some embodiments, the deviation is scaled in reference to the position of the electronic sensor between an X-ray receptor and the X-ray source.

摘要： Phantoms and discrete spatial and frequency methods for quantitatively measuring the alignment of radiographic imaging systems are described. One embodiment comprises phantoms for use in mechanically aligning radiographic imaging systems. These phantoms comprise: a radio-opaque material capable of holding a well-defined edge that allows quantitative image resolution measurements to be obtained thereof; wherein once the quantitative image resolution measurements are obtained, the spatial frequency response of the radiographic imaging system at a given focal plane can be calculated therefrom, thereby defining the mechanical alignment, resolution, and resolution uniformity of the radiographic imaging system. Systems and methods for mechanically aligning radiographic imaging systems, and methods for obtaining a quantitative measurement of the mechanical alignment, resolution and resolution uniformity of radiographic imaging systems, are also disclosed.
