Decomposition of a Tissue Into Its Constituent Elements for Specifying the Values of Doses
Author:
Abstract: In this research, a real tissue has been decomposed to its constituent materials and elements applying its volumetric density and initial mass. This study has been carried out to obtain the exact amounts of constituent elements existing in liver tissue as well as specify the absorbed dose because of the tissue getting exposed to radiation in radiotherapy and radiography. In order, a medical model has been defined in a way that its compositions are just like the materials existing in the tissue of a human. Then, the accurate mass, density, and volume of every element in it are specified. In the next stage, the related tissue is exposed to a neutron beam, and then the values of doses absorbed in the main constituent material namely water, and also the total absorbed dose is obtained by the MCNP nuclear code. This study can be used to study the radiotherapy and radiography scopes for obtaining the absorbed dose as a result of interaction between radiation beam and biological cells. In this research, the values of absorbed doses have been obtained for a wide range of neutron energies in a way that the absorbed doses can accurately be obtained.
