چکیده

Penyinaran radioterapi pada kanker serviks diperlukan perencanaan. Treatment Planning System (TPS) untuk memaksimalkan dosis serap sel dan meminimalkan organ sekitar. Untuk mengetahui distribusi maka simulasi menggunakan Monte Carlo. Carlo metode probabilistik karena perjalanan foton secara acak heterogenitas yang diradiasi. Pemodelan phantom dilakukan mengacu ukuran tubuh wanita dewasa di Asia Taiwanese Reference Woman (TRW). Penelitian ini bertujuan menentukan radiasi sekitar, dengan teknik penyinaran sudut 0˚dan 180˚, serta gabungan dari variasi dalam bentuk kontur berdasarkan target volume (GTV, CTV PTV) ICRU 50. Berdasarkan hasil penelitian dihitung dua 0º 180 º GTV 1,32 Gy, kandung kemih 1,29 0,350 rektum 1,21 Gy. Hasil berada dibawah rentang diperbolehkan yaitu 1,5-2,5 Distribusi maksimum terdapat tepat mengenai memenuhi syarat laporan Dari telah dilakukan, dapat dilanjutkan Multi Leaf Collimator menambah ada bagian perut bawah sehingga sebaran keseluruhan perut.

Monte Carlo N-Particle Method Dose Calculations Using Gold Nanoparticles in Cobalt- 60 Radiation Therapy

In this paper, amplification in dose due to the presence of gold nanoparticles was quantified using Monte Carlo N-Particle (MCNP) simulation. Simulation models included the irradiation of a 30 cm × 30 cm × 15 cm pure-water—volume phantom with a beam of 1.17 MeV and 1.33 MeV Cobalt spectral emissions as source. Planar and concentric water panel detectors placed at a distance of intervals of 0.1 ...

Monte Carlo methods for improper target distributions

Abstract: Monte Carlo methods (based on iid sampling or Markov chains) for estimating integrals with respect to a proper target distribution (that is, a probability distribution) are well known in the statistics literature. If the target distribution π happens to be improper then it is shown here that the standard time average estimator based on Markov chains with π as its stationary distributi...
