A CT image based deterministic approach to dosimetry and radiography simulations.
An integral transport equation based deterministic approach has been developed to compute individual specific absorbed dose distributions and photon flux distributions on a detector for image formation studies. An algorithm has been designed to take advantage of parallel processing platforms capable of processing large amounts of data imposed by the small pixel sizes of CT images. CT images have been used to form voxels that would represent both tissue variations and body geometry. Absorbed dose distributions calculated using the Visible Human dataset are provided.
