Abstract
In this paper the numerical simulation results of the dose spatial distribution of the medical electron beams in ABS-plastic doped with different concentrations of lead and zinc are shown. The dependences of the test material density on the lead and zinc mass concentrations are illustrated. The depth dose distributions of the medical electron beams in the modified ABS-plastic for three energies 6 MeV, 12 MeV and 20 MeV are tested. The electron beam shapes in the transverse plane in ABS-plastic doped with different concentrations of lead and zinc are presented.
Highlights
Radiation therapy uses a wide range of radiation for neoplasms treatment: gamma rays, X-rays, protons, neutrons and electrons [1,2,3,4,5,6,7,8]
In this investigation the electron beam interaction with the ABS-plastic doped with different concentrations of lead and zinc was analyzed
For this purpose the depth dose distribution of the electron beam in the ABS-plastic doped with different concentrations of lead and zinc was calculated
Summary
Radiation therapy uses a wide range of radiation for neoplasms treatment: gamma rays, X-rays, protons, neutrons and electrons [1,2,3,4,5,6,7,8]. One of the most interesting directions of the electron beam medical application is an intraoperative therapy [3] For these purposes it is necessary to have the possibility of beam profile modulation. The presence of the materials with different densities allows to trigger the interaction of the electron beam with human tissue It enables phantoms for experimental methods of the medical procedures planning to develop. For these purposes it is necessary to have the method of tissue-equivalent materials for the human body phantom production. Such requirements are met by rapid prototyping technology [9]
