Hadrontherapy öncü bir
tekniktir ve dünya çapında sadece birkaç merkez bu ileri ve uzmanlaşmış kanser
tedavisini sağlayabilir. Geant4 (GEometry ANd Tracking 4), parçacıkların madde
içindeki etkileşimini simüle etmek için kullanılan C ++, ücretsiz ve açık bir
araç kitidir. Yüksek enerji fiziği, nükleer fizik ve tıbbın çeşitli alanlarında
kullanılmaktadır. Çalışmada, Monte Carlo simülasyon aracı Geant4 ile, gelişmiş
unsurlar kategorisinde modellenen bir proton-tedavi hattının tipik tüm
unsurları olan difüzörler, aralık değiştiriciler, kolimatörler ve detektörler
ile simronterapi ışın hattınının benzetimi yapıldı. Bu benzetim, doz ve Çizgisel
Enerji Transferi (LET) hesaplamasına izin vermiştir. Bu bağlamda bu çalışmada,
Geant4 10.2 sürümü ile gerçekleştirilen benzetimlerimizin ilk sonuçları ve
bunların Cironne tarafından belirlenenlerle karşılaştırılması verilmiştir.

Simulation by Geant4 of hadrontherapy beam line

Hadrontherapy represents a pioneer technique, and only few centers
worldwide can provide this advanced and specialized cancer treatment. Geant4
(GEometry ANd Tracking 4) is a C++, free and open toolkit that used to simulate
the interaction of particles in matter. It is employed in various fields from
high-energy physics, nuclear physics to medicine. By means of Monte Carlo
simulation tool Geant4, we have simulated the hadrontherapy beam line typical
of a proton-therapy line modeled in the category of the advanced examples with
all its elements: the diffusers, range shifters, collimators and detectors.
This Simulation has permited the calculation of dose and Linear Energy Transfer
(LET). In this context, this study reports the first results of our simulation
realized by means of Geant4 10.2 version and their comparizon with those
obteined by Cironne.
