The simplest way would likely to be creating a new output function once your phantom has been constructed.
Assuming you are using the nested parameterisation (low memory, fast), then the important bits of code can be found in "DicomNestedParamDetectorConstruction.cc/.hh"
In the .cc file, you should see the lines (104-121):
G4ThreeVector voxelSize(fVoxelHalfDimX,fVoxelHalfDimY,fVoxelHalfDimZ); DicomNestedPhantomParameterisation* param = new DicomNestedPhantomParameterisation(voxelSize, fMaterials);
new G4PVParameterised("phantom", // their name logicVoxel, // their logical volume logXRep, // Mother logical volume kZAxis, // Are placed along this axis //kUndefined, // Are placed along this axis fNVoxelZ, // Number of cells param); // Parameterisation.
param->SetMaterialIndices( fMateIDs ); param->SetNoVoxel( fNVoxelX, fNVoxelY, fNVoxelZ );
Here, the CT file has been read, and voxels have been mapped to their respective materials.
What you could do is create a new function in this cc file (and its declarationin the header file) like: void DicomNestedParamDetectorConstruction::printPhantom()
In such a function, you would want to do for loops through nx, ny, nz (or nxyz=nx*ny*nz), where you print the voxel index, as well as fMaterials[fMateIDs[i]]->GetDensity(); //something like this line
Basically what that will do is take the index of the voxel, get the material ID from the fMateIDs vector, and grab that material from the fMaterials vector. Then you can just print the density. You may also consider writing the densities to a binary block of data, and out putting that using a file i/o command.
