A method for producing an image in a x-ray imaging system is provided. The x-ray
imaging system includes an x-ray source which projects an x-ray beam collimated
by a collimation assembly to pass through an object and impinge on an x-ray receptor
to produce the image. The method includes rotating the collimation assembly about
a focal point while the x-ray source is substantially fixed and producing x-rays.
The method further includes adjusting the position of the x-ray receptor during
rotation of the collimation assembly to receive the x-ray beam.
