A method is developed by which the computed tomography scans of a medium carried out at a number of diagnostic energies can be utilized to obtain the insitu “Effective Atomic Number” and “Effective Density”. The electron depth dose curves in water when scaled by these factors estimate the actual electron depth dose distribution in that medium. It appears that the use of CT scans for electron beam treatment planning, in the management of cancer, is quite promising.
