Monte Carlo study of a highly efficient gas ionization detector for megavoltage imaging and image-guided radiotherapy.
The imaging characteristics of an arc-shaped xenon gas ionization chamber for the purpose of megavoltage CT imaging were investigated. The detector consists of several hundred 320 microm thick gas cavities separated by thin tungsten plates of the same thickness. Dose response, efficiency and resolution parameters were calculated using Monte Carlo simulations. The calculations were compared to m...
متن کاملA fast model for prediction of respiratory lung motion for image-guided radiotherapy: A feasibility study
Background: The aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one CT dataset. Materials and Methods: For each of six patients with different thorax sizes, two sets of CT images were obtained in single-breath-hold inhale and exhale stages in the supine position. The CT images were then ...
متن کاملMonte Carlo Study of Radiation Dose Enhancement by Gadolinium in Megavoltage and High Dose Rate Radiotherapy
MRI is often used in tumor localization for radiotherapy treatment planning, with gadolinium (Gd)-containing materials often introduced as a contrast agent. Motexafin gadolinium is a novel radiosensitizer currently being studied in clinical trials. The nanoparticle technologies can target tumors with high concentration of high-Z materials. This Monte Carlo study is the first detailed quantitati...
متن کاملA performance study of the conceptual implementation of the GEM-tracking detector in Monte Carlo simulation
PANDA experiment (antiProton ANnihilation at DArmstadt) is one of the key projects of the future FAIR facilities to investigate the reactions of antiprotons with protons and nuclear targets. experiment is designed to serve as a completely extraordinary physical potential due to exploiting the availability of cold and high-intensity beams of antiprotons. One of the significant parts of the ...
متن کاملMegavoltage dose enhancement of gold nanoparticles for different geometric set-ups: Measurements and Monte Carlo simulation
Background: Gold nanoparticles (GNPs) have been shown as a good radiosensitizer. In combination with radiotherapy, several studies with orthovoltage X-rays have shown considerable dose enhancement effects. This paper reports the dose enhancement factor (DEF) due to GNPs in 18 megavoltage (MV) beams. Materials and Methods: Different geometrical 50-nm GNPs configurations at a concentrati...
