Abstract:
Hadron therapy is a form of radiotherapy in which the irradiating beams are made of heavy charged particles, such as protons and heavy ions. These particles, due to their characteristic interaction mechanisms, have a substantial potential to deposit a higher dose in a particular area with a minimum effect on the surrounding healthy tissues. In this study, SRIM (Stopping and Range of Ions in Matter) code was used to obtain Bragg curves using ions such as Hydrogen, Helium, Lithium, Carbon and Neon of energies of 10, 20, 40, 80 and 160 MeV/nucleon in bone, adipose tissue, spleen and pancreas. The dependence of the stopping power, the Bragg peak position and range on the incident energy, type of projectile and type of tissue will be presented and discussed. By using a simulated multilayer target, we have irradiated with different proton beam energies the thyroid tissue and found the most suitable proton energy interval for this specific geometry to obtain the Spread Out Bragg Peak (SOBP).
