To make optimal use of the advantages of proton beams in tumor therapy a precise knowledge on their range is required. Recently, a slit camera has been developed using prompt gamma rays emitted during irradiation. First investigations in homogeneous media have shown that the position of the distal falloff of the prompt gamma ray profiles is closely correlated with the Bragg-peak position. Now, heterogeneous targets are under investigation and first results on detectability of range shift as well as range retrieval precision will be presented.
