RESUMO

Objective To study the impact of implanted thermoseeds of magnetic induction hyperthermia on radiation dose distribution. Methods To simulate irradiation, an anthropomorphic phantom and three-dimensional treatment planning system were used. The impact of thermoseeds on radiation dose distribution was evaluated. Results The change of absorbed dose caused by the implantated thermoseeds was less than 1.5%. Conclusions The impact of implanted thermoseeds on radiation dose distribution is small and comes up to the requirements that the total target dose uncertainty must be less than 5%. Therefore, the impact of thermoseeds on the absorbed dose in tissue can be ignored in clinical practice.

RESUMO

This article describes the physical, technical, and dosimetric aspects of total body irradiation (TBI) that was carried out by using 6MV X-Ray from Varian 2300 C/D Linear Accelerator at a distance of 450 cm from target to the treatment table and at a gantry angle of 270°.The dose to lung tissue was limit by setting the individual lead compensators customized before, and using DPD-510 to monitor the absorbed dose of the reference point the absorbed dose in depth of half of body will be (Din+Dout)/2 after taking treatment in both AP position and PA position.
