Presenting and simulating an innovative model of liver phantom and applying two methods for dosimetry of it in neutron radiation therapy.

Aim: A new model of liver phantom is defined, then this model is simulated by MCNPX code for dosimetry in neutron radiation therapy. Additionally, an analytical method is applied based on neutrons collisions and mathematical equations to estimate absorbed doses. Finally, the results obtained from two methods are compared to each other to justify the approach.
