Description

Apparatus is claimed for constructing a representation of the variation of attenuation of penetrating radiation in a planar slice of an object positioned in a scan circle. It comprises means for generating sets of data, each set representing a characteristic of the attenuation of a fan-shaped swath of paths of radiation passing through the scan circle. Each swath has an apex at one of a plurality of angular positions around the scan circle. The angular positions of the apices span an arc of between 180 and 360 degrees. There is a means operatively connected to the generating means for convolving each set of data and means for transforming the convolved sets of data into the representation
