摘要：
A device for reconstructing the absorption distribution in a three-dimensional body. The body to be examined is imaged from two groups of radiation source positions. Each group of radiation source positions is situated on an arc of a circle around the axis of rotation, and the acrs of a circle determine the dimensions of the region in which the absorption distribution is reconstructed. The detector device is disposed between the two arcs of a circle.
