This article describes a technique in which X ray transmission readings are taken through the head at a multitude of angles: from these data, absorption values of the material contained within the head are calculated on a computer and presented as a series of pictures of slices of the cranium. The system is approximately 100 times more sensitive than conventional X ray systems to such an extent that variations in soft tissues of nearly similar density can be displayed.
