| Abstract: | The absolute percent differences between the total scan point efficiencies at the point of voxel center and at the boundary between layers are calculated for 6 different collimators using Monte Carlo methods. A diamond shaped collimator and a trimmed diamond collimator are selected as the collimator of TGS device. |
