Purpose: Gold nanoparticles (GNP) have significant potential as radiosensitizer agents due to their distinctive properties. Several studies shown that the surface modification of with methyl polyethylene glycol (mPEG) can increase biocompatibility. However, present study investigated radiosensitization effects mPEG-coated GNP (mPEG-GNP) in B16F10 murine melanoma cells under irradiation 6 MeV Electron beam.Materials and methods: The synthesized were characterized by UV-Visible spectroscopy,...
Abstract Background Brachytherapy of thin skin tumors using beta particles can protect underlying sensitive structures such as the bone because rapid dose falloff this type radiation in tissue. The current work describes a brachytherapy applicator, based on radiation, that provide needed cell‐killing matched to shape individual tumors. Materials and methods applicator its template were fabricated 3D printing technology. Any clinically approved beta‐emitting isotope form radioactive gel could...
Abstract This study evaluated the basic dosimetric characteristics of a Dynamic Multi Leaf Collimator (DMLC) using diode detector and film measurements for Intensity Modulated Radiation Therapy Quality Assurance (IMRT QA). The EGSnrc Monte Carlo (MC) simulation system was used determination MLC characteristics. transmission abutting leaf leakage relevant to LinaTech DMLC H were measured an EDGE EBT3 film. In this study, BEAMnrc code modeling. head Siemens PRIMUS linac (6 MV) with external...
Abstract Introduction MRI is preferred for brain tumor assessment, while CT used radiotherapy simulation. This study evaluated immobilization equipment's impact on CT‐MRI registration accuracy and MR image quality in RT setup. Methods We included images from 11 patients with high‐grade glioma, all of whom were immobilized a thermoplastic mask headrest. T1‐ T2‐weighted acquired using an head coil diagnostic setup (DS) body matrix To assess quality, signal‐to‐noise ratio (SNR)...
Abstract Background Intraoperative radiotherapy is a method of choice to deliver critical radiation dose the tumour bed immediately after surgical excision. Aim The purpose this work check delivered patients during intraoperative electron beam therapy (IOERT) in conservative treatment breast cancer, by means reference measurement using radiochromic (EBT-2) films. Material and methods Ninety with early-stage cancer underwent exclusive IOERT LIAC linear accelerator. Absolute measurements were...
Nowadays, some nanoparticles (NPs) are known and used as radiosensitizers in radiotherapy radiobiology, due to their desired biological, physical, chemical effects on cells. This study aimed evaluate compare the dose enhancement factor (DEF) biological effectiveness of common NPs through EGSnrc MCDS Monte Carlo (MC) simulation codes.
