Abstract
An x-ray-based radiation imaging apparatus (200) for use in imaging an object (201) can comprise a source of x-rays (202) having an output radiation intensity control input and a radiation intensity controller (207) operably coupled thereto. This radiation intensity controller can have a control output (209, 210) that is operably coupled to the output radiation intensity control input and an object information input (209). So configured, the radiation intensity controller can dynamically adjust radiation intensity as output by the source of x-rays as a function of information regarding the object itself.
