Summary:Methods and systems for scanning objects comprising scanning a portion of an object by a first radiation beam having a first value of a beam characteristic, such as the dose, and detecting the first radiation beam after interaction with the object by a first detector. It is determined whether to change the first value to a second value based, at least in part, on the detected first radiation beam. That portion of the object is then scanned by a second radiation beam having the first value or the second value based on the determination. The second radiation is detected after interacting with the object by a second detector. The second detector may have a second resolution greater than a first resolution of the first detector. The first and second radiation beams may be formed by first and second slots angled with respect to each other.
