Abstract

It is important to get sufficient thermal neutron flux at the tumor for the purpose of increasing the efficiency of NCT. To improve the effect of the treatment for a tumor deeply seated in a human body, the distribution of thermal neutron fluence should be improved. In this paper, we studied on the methods for increasing the thermal neutron doses at the deep location from the viewpoint of the physics and engineering.
