I changed the size of phantom to 40cm*40cm*40cm.
And changed the size of detector to 40cm*40cm*40cm.
To detect energy deposit in each voxel, which is 1cm, I changed the voxel sizes(x,
y, and z).
So, I got a 3D DoseDistribution.out file.
Here, I got a question.
I fount that the voxel number is from 0 to 79.(maybe the final number is 80).
I was confused why the voxel number reached 80 not 40.
In my opinion, the final voxel number should be 40. (1cm * 40 voxels = 40 cm)
In HadrontherapyDetectorConstruction.cc file, I found that
numberOfVoxelsAlongX = lrint(2 * detectorSizeX / sizeX); sizeOfVoxelAlongX = (2 * detectorSizeX / numberOfVoxelsAlongX );
I can't understand why we should multiply 2.
The length of each voxel is the same with voxel size? or half of the voxel size?
