In 2001, the use of cylindrical coordinates was demonstrated to be more suitable than was the use of polar coordinates for accurate computer calculations during treatment planning for 192Ir intravascular brachytherapy sources. In the present work, we investigated the applicability of cylindrical coordinate-based TG-43U1 parameters for dosimetric evaluation and dose calculations for RadioCoil 10...

in this paper, we examine the effect of the energy difference between the l- and the -valleys in compound semiconductor materials, carrier effective mass, and the scattering processes on the electron transport characteristics in mesfets. to do this, we use the monte carlo simulation to demonstrate the superiority of the ingaas mesfet, made on a semi-insulating inp substrate, over both inp and ...

Introduction: The use of low energy isotopes such as  103 Pd in brachytherapy for the treatment of cancers  such as prostate, eye, head, neck, breast and cervix is increasing. In this regard, different models of Pd- 103  seeds  have  been  designed  and  manufactured  at  the  Agricultural,  Medical  and  Industrial  Research  School (AMIRS) of Atomic Energy Organization of Iran. In this resear...

A simplified approach is proposed to simulate the fluorescence signal from a fluorophore submerged inside a turbid medium using the Monte Carlo method. Based on the reversibility of photon propagation, the fluorescence signal can be obtained from a single Monte Carlo simulation of the excitation light. This is computationally less expensive and also allows for the direct use of well-validated n...

Monte Carlo techniques have become popular in different areas of medical physics over the last 50 years. Factors which have contributed to the wider use include the improved description of radiation transport as well as the optimization of the computing systems. The main advantage of Monte Carlo methodology deals with the simulation of stochastic processes involving random behavior and the quan...
