Abstract

Computed Tomography (CT) images taken in cancer treatments are important in treatment portal design and planning. The dose received by the patient in CT scans are not considered in the treatment planning dose calculation and becomes important in calculating the limit doses of the critical organs with critical dose threshold. In this study, the change of the dose received by some of the critical organs, namely the heart, liver, and kidneys, according to the height of the patient was investigated with the NCICT code using the Monte Carlo technique. As a result, doses were changed by the height of the patients.

CT Taramalarında Hastanın Boyuna Göre Absorbe Edilen Dozun Değişimi

Abstract

Kanser tedavilerinde çekilen Bilgisayarlı Tomografi (CT) görüntüleri, tedavi portalı tasarımı ve planlamasında önemlidir. Hastanın CT taramalarında aldığı doz, tedavi planlaması doz hesaplamasında dikkate alınmaz ve kritik doz eşiğine sahip kritik organların sınır dozlarının hesaplanmasında önem kazanır. Bu çalışmada bazı kritik organlar olan kalp, karaciğer ve böbreklerin hastanın boyuna göre aldığı dozun değişimi Monte Carlo tekniği kullanılarak NCICT kodu ile araştırıldı. Sonuç olarak, dozlar hastaların boyuna göre değiştirildi.
