The invention relates to a data processing system 2 for determining a distribution of a tracer uptake, comprising image processing means 4 arranged for scoring partial volumes of the target region from one or more PET images comprising a suitable target region as a function of parameter values representative of a tracer uptake in said partial volumes. The data processing system 2 further comprises computing means 6 arranged for determining a distribution of said partial volumes over said parameter values. For this purpose, first, the computing means may be arranged to determine a range of the parameter values. Secondly, the computing means may be arranged to compute relative (percentage) parameter values with respect to the maximum parameter value identified in the range. Thirdly, the computing means may be arranged to relate the partial volumes having substantially the same parameter value or relative parameter value with said parameter values. Preferably, such relation is stored in a memory unit 7 as a cumulative or binned histogram. The invention further relates to an arrangement comprising the data processing system 2 and a PET scanner 1. The invention still further relates to a method and a computer program product for determining a distribution of a tracer uptake. |
