ABSTRACT:
In a radiological apparatus wherein radiation is passed through a body along a plurality of co-planar paths, attenuator means is utilized to tend to compensate for differences in the lengths of said paths within a body being examined. The attenuator means, however, introduces a variation into the radiation spectrum and the invention provides means for compensating for such variation. Such compensating involves processing output signals derived from detector means disposed to receive the radiation after it has traversed the body and the attenuator means.
