Left: β+-activity profiles obtained by MC simulation and in-beam PET measurement, normalized to the maximum, as well as the corresponding dose profile are shown. The blue lines denote the location of the activity maximum, the 50 % dose fall-off (vertically, left to right) and the 20 % activity limit (horizontally). Right: The profile difference Ddiff is visualized as function of the profile shift for different analysis starting depths zmin.

    Article Snippet: In the following section, the basic principles of the range verification methods by ( Knopf et al. 2008 ) and ( Min et al. 2013 ) are reviewed, which are used in the development of the MLS approach and applied to the investigated data, respectively.

    Techniques: Activity Assay

    Range verification of the proton-irradiation induced activity in P7. (a) Exemplary sagittal planes of the simulation (top) and the offline PET measurement (bottom) are displayed. (b) The corresponding normalized activity depth profiles are shown together with the dose profile. The activity fall-off thresholds of 25 % and 50 % are marked by blue lines. (c) The MLS results (top) show only small deviations in most parts of the distribution compared to the MP (bottom) calculations.
