摘要
Methods and an x-ray system for dynamically regulating x-ray dose. An x-ray beam is generated and collimated at a source collimator and detected after the x-ray beam traverses an inspected object. A filter may be dynamically interposed by translation of the filter between a focal spot of the source and the source collimator in such a manner as to maintain the portion of the x-ray beam that traverses the inspected object below a specified limit. Alternatively, an aperture of the source collimator may be varied in size or position relative to the focal spot.
