Dosimetric Evaluation of Target Volume in Breast Boost Radiotherapy: Comparison of Electron and Photon Beam

Background and purpose: Breast‑conserving surgery followed by radiation therapy to the whole breast is now recognized as a standard strategy in patients with breast cancer. Recommended technique for radiotherapy is whole breast irradiation followed by boost to the tumor bed. This study aimed to compare the dosimetric parameters of electron and photon beams for boosting irradia­tion in post‑lump...

Evaluation of Electron Contamination in Cancer Treatment with Megavoltage Photon Beams: Monte Carlo Study

Background: Megavoltage beams used in radiotherapy are contaminated with secondary electrons. Different parts of linac head and air above patient act as a source of this contamination. This contamination can increase damage to skin and subcutaneous tissue during radiotherapy. Monte Carlo simulation is an accurate method for dose calculation in medical dosimetry and has an important role in opt...

Estimation of Secondary Skin Cancer Risk Due To Electron Contamination in 18-MV LINAC-Based Prostate Radiotherapy

Introduction Accurate estimation of the skin-absorbed dose in external radiation therapy is essential to estimating the probability of secondary carcinogenesis induction Materials and Methods Electron contamination in prostate radiotherapy was investigated using the Monte Carlo (MC) code calculation. In addition, field size dependence of the skin dose was assessed. Excess cancer risk induced by...

Modeling and simulation of a laser deflecting system

In this report a model of Differential and Algebraic Equations (DAE) for the dynamics of a rotating laser deflecting system, which is a multibody system, is derived. Classical numerical integration software isn't however able to solve these equations, so the possiblity to transform the model into a set of Ordinary Differential Equations (ODE) is investigated. Elimination of the algebraic equati...
