Özet

Bu araştırmada amaç; endometrium, serviks ve larinks kanserlerinin yoğunluk ayarlı radyoterapi (YART) tekniğinde 6 farklı homojenite indeks formülleri kullanılarak hesaplanan değerleri karşılaştırmak ve doz homojenitesi için en iyi homojenite indeksini belirlemektir.

Abstract

The aim of this study is to compare results that are calculated using 6 different homogeneity index formulae for Intensity Modulated Radiation Therapy (IMRT) in endometrium , cervix and larynx cancers and to determine the best homogeneity indices for dose homogeneity.In this study 6 different homogeneity index formulae were evaluated for 30 patients for endometrium, cervix and larynx cancer patients receiving dynamic Multileaf Collimator (dMLC) Intensity Modulated Radiation Therapy (IMRT) treatments on ELEKTA SYNERGY linear accelerator with 6 MV photon beam. Intensity Modulated Radiation Therapy (IMRT) plannings were carried out on MONACO treatment planning system. The factors that could effect the homogeneity indices were examined. The data obtained that were analyzed with Statistical Package for the Social Sciences (SPSS) statistical programme.
