Evaluation of Absolute Doses in Spread-Out Bragg Peaks for Therapeutic Carbon Ion Beams

M. Sakama, T. Kanai, A. Fukumura & Y. Kase
In particle therapy with the passive scattering methods, Spread-Out Bragg Peaks (SOBP) with the ridge or wheel filter was used to achieve the uniform biological effect for the irradiated tumor. Therefore there are the primary and fragment particles with variable energies in SOBP. In current dosimetry[for full text, please go to the a.m. URL]
