Monte Carlo study on megavolt x-ray therapy for development of suitable targets for the evaluation of nano particle dose enhancement
(University of the Free State, 2016-09)
English: INTRODUCTION: Radiation dose enhancement with nanoparticles is a treatment technique
involving the irradiation of tumour seeded with high atomic number (high Z) material. This work
describes the generation of ...
Using Monte Carlo techniques to evaluate the dose distributions from a radiotherapy treatment planning system
(University of the Free State, 2000-06)
English: In this study we used Monte Carlo techniques to simulate the SL25 linear accelerator
treatment head using the BEAM Code. The main purpose of study was to evaluate the
dose distributions obtained by the CADPLAN ...
Development of a Monte Carlo simulation method for the evaluation of dose distribution calculations of radiotherapy treatment planning systems
(University of the Free State, 1999-11)
In this study a method is described whereby the dose distributions calculated by any
treatment planning system (TPS) could be evaluated using dose distributions calculated
with Monte Carlo simulations. The Monte Carlo ...
Monte Carlo evaluation of the dose perturbation effect of various hip prostheses during pelvic megavoltage photon radiotherapy
(University of the Free State, 2016-11)
English: Introduction: Hip prostheses (HPs) are routinely used in hip augmentation surgery to replace painful or dysfunctional hip joints, especially in the elderly population. A number of patients with HPs are undergoing ...
Sensitivity analysis of the intergral quality monitoring system® for radiotherapy verification using Monte Carlo simulation
(University of the Free State, 2017-07)
Advanced radiotherapy (RT) techniques have improved the quality of radiation treatment. Notwithstanding, advanced RT techniques have generated complexities in their quality assurance (QA). Therefore, there is a huge interest ...
Feasibility of tissue differentiation with multi-energy computed tomography: a Monte Carlo breast phantom study
(University of the Free State, 2017-03)
English: Dedicated breast CT is a new innovative way of imaging breast tissue without the limitations of overlapping anatomical features. It has been shown that the dose received by the patient is comparable to that of ...
Evaluation of a commercial radiation oncology treatment planning system against Monte Carlo simulated dose distributions
(University of the Free State, 2007-11)
English: A method is described in this study whereby dose distributions calculated by a treatment planning system (TPS) were evaluated by using dose distributions calculated with Monte Carlo (MC) simulations. The MC ...
Development of a particle source model for a synergy linear accelerator to be used in Monte Carlo radiation dose calculations for cancer therapy
(University of the Free State, 2014-05)
English: In oncology patients are treated for cancer with various methods such as surgery, chemo
therapy and radiation therapy. Accurate radiation treatment planning and dose delivery to the
tumour is necessary for the ...
Verification of a commercial treatment planning system based on Monte Carlo radiation dose calculations in intensity modulated radiation therapy
(University of the Free State, 2015-01)
English: Cancer treatment with external beam radiotherapy using the specialized technique of intensity modulation is a complex modality. The Treatment Planning System (TPS) is responsible for accurate calculation of dose ...
