Abstract

With the development of radiotherapy (RT), linear electron accelerators have almost replaced cobalt machines. Therefore, treatment planning methods and techniques of dose delivery to the tumor have changed. Comparison of different methods of RT based on computer simulation was carried out in the paper. On the example of a real patient, it is shown that intensity-modulated RT has certain advantages compared to 3D conformal RT.

Simulation has shown that it is better to use the intensity-modulated RT technique in irradiation of tumors in the neck area since using 3D conformal RT increases treatment duration and dose, i.e. the load on critical organs.

Thus, the minimum dose, received by various targets (tumor bed GTV, clinical target volume CTVmod, and clinical target volume along with surrounding lymph nodes CTV1mod) at intensity-modulated RT is lower by 7.9%, 28% and 35.4% respectively, than at 3D conformal RT. Therefore, radiation dose decreases differently, namely, the larger the target the greater the reduction. So, when planning treatment, it is necessary to weigh positive and negative effects for a particular patient since selecting irradiation technique is always a compromise between saving critical organs and the optimal dose distribution in different targets.
