PCT (Proton Computed Tomography) is a toolkit used to process proton CT data and reconstruct proton stopping power maps. PCT is written both in C++ and Python, and is designed to be used either as a code library, or with command-line applications.
PCT can be installed from source from its git repository hosted at GitHub. The command to clone the repository is:
git clone https://github.com/RTKConsortium/PCT.gitConfiguration and compilation is handled via CMake. Configuration can be achieved using
cmake path/to/source/folder # where PCT was clonedor using a graphical tool such as ccmake. Once configuration completes, the compilation can be achieved using
makeKeep in mind that make can be sped-up using the -j option, allowing to parallelize the compilation, for instance using make -j 4 if your computer has 4 cores.
Optionally, PCT can be added to the user's $PATH variable using for instance
export PATH=path/to/build/folder:${PATH} # where PCT was builtin the user's .bashrc file.
Some functionalities of PCT require GATE to run. Instructions on how to install GATE can be found in the GATE documentation. An example of proton CT GATE simulation can be found here.
Usage of each PCT application can be described using the --help/-h option. For instance, running
pctfdk --helpdisplays the help for pctfdk.
Reconstruction typically involves the following steps:
pctpairprotonsin order to arrange ROOT data in a format described here.pctpaircutsin order to remove nuclear collisions.pctbinningin order to compute the distance-driven binning as described here.pctfdkin order to reconstruct the data generated in the previous step using distance-driven FDK (as described here).
