ABSTRACT
The ion beam is used to treat regions of interest in organ material (Fukumura et al. 1998, Iseki et al. 2003, Rebisz-Pomorska et al. 2010). This chapter investigates the behavior of nanoscale ions with respect to their interaction with cancer cells. The optimized dose is classi•ed according to several variables such as beam energy, cell properties, cancer cell depth, and so on. Successful treatment is expected in clinical results. It is important to make the spread out Bragg peak for the therapeutic radiation distribution. Pristine peaks are summed to reveal the optimized broad shape. The purpose of the beam shapes is to •t the target area. It is important to shape to match the dimensions of the tumor, and thus deliver most of the radiation to the targeted tumor mass, not to the surrounding normal tissue. For this purpose, it is necessary to produce several ion beams. Although this is a simple method, the cost of ion beam production will increase. In this chapter, the characteristics of ion beams are classi•ed by ionizations, energy to recoil, and phonons. This chapter discusses a radiation therapy protocol using the Bragg peak where computerized simulations are performed with Stopping Range of Ions in Matter (SRIM) 2008. The results are calculated simply and cheaply using the SRIM 2008 computational code.
