Abstract
In one illustrated embodiment two detector arrays are arranged in parallel and only one detector array is impinged upon by the primary radiation beam, the second detector array detecting only the scatter radiation due to the primary beam. Preferably, the second detector array is arranged so as to receive substantially a maximum intensity essentially equal to the scatter radiation impinging on the first detector array. In one example, the output of the second detector array may be simply subtracted from the output of the first detector array so as to obtain an accurate measure of the transmitted primary radiation. In an alternative embodiment, a single detector array is shifted to a second position for detecting only scatter radiation substantially corresponding to the scatter radiation mixed with the transmitted primary radiation.
