Endometrium, serviks ve larinks kanserlerinin yoğunluk ayarlı radyoterapi tekniğinde doz homojenite indeksinin kantitatif olarak değerlendirilmesi ve homojenite indeks değerlerinin karşılaştırılması

Öz

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.

Bu calışmada, ELEKTA SYNERGY lineer hızlandırıcısında 6 MV   foton enerjisi ile dinamik Multi Lif Kolimatör (dMLC) yoğunluk ayarlı radyoterapi (YART) tedavi tekniği ile tedavi edilen 30 hastanın (10 endometrium, 10 serviks, 10 larinks) 6 farklı formülle hesaplanan homojenite indeks sonuçları değerlendirilmiştir. Yoğunluk ayarlı radyoterapi (YART) planları MONACO tedavi planlama sisteminde planlanmıştır. Ayrıca, homojenite indeksini etkileyen faktörler de incelenmiştir. Elde edilen veriler Sosyal Bilimler İçin İstatistik Programı (SPSS) istatistiksel analiz programı yardımıyla analiz edilmiştir.

Comparison of homogeneity indices for quantitative evaluation of dose homogeneity for ımrt treatments of endometrium, cervix and larynx cancers

Öz

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.
