Background: Brachytherapy treatment planning in cervix carcinoma patients using two dimensional (2D) orthogonal images provides only point dose estimates while CT-based planning provides volumetric dose assessment helping in understanding the correlation between morbidity and the dose to organs at risk (OARs) and treatment volume. Objective: Aim of present study is to compare Internationa...

Telah dilakukan penelitian mengenai distribusi dosis radiasi foton pada Treatment Planning System (TPS) menggunakan teknik Three Dimension Conformal Radiotherapy (3DCRT) dan Intensity Modulation (IMRT) untuk terapi kanker serviks, ini bertujuan mengetahui yang mencangkup Target Volume (PTV) ) Cakupan melalui Conformity Index (CI) Homogeneity (HI) serta Normal Tissue to Integral Dose (NTID) jari...

Modern radiotherapy relies on accurate dose delivery to the prescribed target volume. The ICRU has recommended an overall accuracy in tumour dose delivery of ±5%, based on an analysis of dose response data and on an evaluation of errors in dose delivery in a clinical setting. Considering all uncertainties involved in the dose delivery to the patient, the ±5% accuracy recommendation is by no mea...

To understand the performance of a sensor or make a choice between different sensors for a detection task it is important to have an understanding of how the recorded signals are generated. In the case of sensing ionizing radiation, signals are generated after the incoming radiation has undergone interactions within the sensor material. The types of interactions and the subsequent resultant par...

Background: Best dose distribution in target volume and control of Organ at Risk (OAR) dose are the two main goals in brachytherapy. Materials and Methods: In this study in vivo dosimetry in 4 rectal points was performed by Transillumination Dosimeter (TLD) s and the measured doses were compared in different patients. One point was reported to have the maximum dose in each patient and the very ...

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...

As clinical trials of Neutron Capture Therapy (NCT) are initiated in the U.S. and other countries, new treatment planning codes are being developed to calculate detailed dose distributions in patient-specific models. The thorough evaluation and comparison of treatment planning codes is a critical step toward the eventual standardization of dosimetry, which, in turn, is an essential element for ...
