In this example a list of DICOM files (.dcm) are converted to ASCII files (.g4dcm) and binary (.g4bin) that can be read by GEANT4. Then, these files are used by GEANT4 to construct patient geometry. The geometry is constructed by voxelizing computed tomography data. Four navigation algorithms are available to create the voxel geometry: G4SmartVoxel, G4VNestedParameterisation, G4PhantomParameterisation and G4Replica. In this tutorial we investigate the efficiency of the different algorithms. |
