Carbon ion (270.55 MeV/u) trajectories in an FNTD exhibiting stochastics energy loss, delta electrons, and a fragmentation event (Lauer, 2011): 'Traveling trajectories with crystals made of ion' (from: Jedi Mind Tricks: Merchant of War, The Thief and the Fallen, 2015)

The purpose of the DKFZ FNTD project is to exploit and advance the use of fluorescent nuclear track detectors (FNTDs) in proton and ion-beam therapy. One major focus hereby is the development of a software package for track data analysis.


Our software uses ImageJ and its [Mosaic] plugin as a class library. The core functions are written in Java and bundled in a single jar-file (the library). This library can be used as standalone (called from shell / command line), plugin for ImageJ and Fiji, and as an extension package to the R language (the package). The latter enables scripting (i.e. high-throughput usage) and extensions of the library functions such as automated generation of reports. In principle, any language with access to Java can be used for this purpose.

In April 2017, major changes have been made to the library and older version of the software has been branched as 'classic' version to maintain the ability to run older analyses. Both the library and the R package are open-source and hosted on github.
