Abstract

Background: In this research dosimetric parameters of MERCURY were investigated as a radiotherapy modulator and compared with CERROBEND as a common beam attenuator material in most radiotherapy centers.Materials and methods: In this experimental study, transmission factor of different thicknesses of CERROBEND and MERCURY at 6MV and 18MV photon beams were measured in order to investigate MERCURY as a beam modulator. Relative DOSIMETRY was done with ionization chambers and then MERCURY modulating system for radiotherapy was designed with different cross sections.Results: The DOSIMETRY results show that the transmission values increased with field size increment due to increased scatter contribution, for all CERROBEND and MERCURY thicknesses. The procedure of MERCURY transmission factor is in agreement with CERROBEND transmission factor. The second designed system with hexagonal cross section is in good agreement with patient contour.Conclusions: The experimental investigation on MERCURY dosimetric parameters showed that MERCURY could be proposed as a modifier in radiotherapy because of its profit properties such as being liquid in room temperature and power of attenuation. So MERCURY can be proposed as a beam modifier (at closed system because of its poison vapor) in radiotherapy.
