Figure Lengend Snippet: Basics of range verification, exemplarily shown for the voxel coordinates (x, y) = (70,59) in patient P3 (cf table 1). 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
