WitrynaIntensity-modulated radiation therapy (IMRT) is a type of conformal radiotherapy that uses a linear accelerator to deliver an advanced type of high-precision radiotherapy that shapes the radiation beam to closely fit the area of the tumour. WitrynaIMRT signiﬁcantly reduced the irradiated volume of OAR and improved dose conformity in the PTV compared to that by 3DCRT. So, it can be concluded that IMRT should be chosen as preferred technique for the EBRT of LACC with proper immobilizing devices and imaging.
