Method of and device for measuring the distribution of a radiation in a plane of a body

Abstract From the Canadian patent

In the reconstruction of the absorption values in the various picture elements of a plane under examination from measured values which were measured by means of a scanner for transversal tomography it is neces-, sary to assign to each picture element from each measured series (at a given angle with respect to the examination plane) at least one intermediate value. This means in general that an intermediate value has to be computed with up to three measured values and weight factors. This requires very much computing time. The invention describes a way which requires less computing time in which by the interpolation the intermediate values which are assigned to the various picture elements …
