Abstract

Treatment plans can differ widely depending on whether they were developed from anatomical information generated by computed tomography or conventional transverse axial tomography. Deviations between [human] tumor doses calculated using the 2 methods were as great as 10%, increasing to 20% for the spinal cord.
