ABSTRACT:
For measuring the absorption from measuring values whereby the radiation attenuation in a plane of a body is measured, a large number of calculations must be performed. When use is made of a digital computer, a large quantity of storage locations and a long calculating time are required. According to the invention, use is made of a charge storage tube wherein the correction values calculated in a preprocessing unit on the basis of the measuring values are superimposed, so that a substantial reduction of the calculation time and a reduction of the number of storage locations are realized.
