Pre-clinical studies (keV)
Bazalova and Graves. MP 38 June 2011
120kV, 225kV, 320kV and Ir-195 on centrally located lung tumour
in small animal
Conclude: Tissue segmentation based on mass density leads to
Errors of up to 27% for 120kV
Need tissue segmentation based on effective atomic number and
39 tissues to get below 2%
