Abstract:
1. A method of X-ray imaging an object, comprising generating first and second imaging beams; scanning the first and second imaging beams over the object with the second beam following the first beam; recording an image of the object with the first beam over a plurality of regions of interest, each region of interest including a plurality of pixels; calculating at least one parameter for each of the regions of interest; varying the second beam for each of the regions of interest based on the respective calculated parameters; recording an image of the object with the second beam over the plurality of regions of interest; and combining the images recorded by the first and second beams, wherein: the first beam is a fan beam extending in a first beam direction; the second beam is a fan beam extending in a second beam direction; and the first and second beam directions are substantially perpendicular to each other.
