Evaluation of occupational and medical dose on interventional cardiology procedures by Monte Carlo method

چکیده
A cardiologia intervencionista é um conjunto de procedimentos médicos que tem como principal foco diagnosticar e tratar pacientes com problemas cardiovasculares. Embora o uso dos raios X neste caso seja justificado, é de grande importância fazer uma avaliação das doses tanto nos pacientes quanto nos profissionais envolvidos, pois as doses podem ser altas, uma vez que, na maioria dos casos, os procedimentos são demorados e complexos. O objetivo deste trabalho é estimar a dose de radiação numa paciente e em uma médica através de coeficiente de conversão de dose (CCs) equivalente (H) e efetiva (E) durante exame de angiografia coronária. Os CCs de dose foram simulados através do código Visual Monte Carlo (VMC) e uma dupla de simuladores antropomórficos voxel (Female Adult voXel). Os CCs de dose foram normalizados em termos do produto kerma-área (KAP). Como esperado, para todas as situações estudadas, a projeção anteroposterior (AP) apresentou os maiores valores de CCs de dose equivalente e dose efetiva para a paciente.

Abstract: Introduction: Chest radiography is one of the most common X-ray imaging procedures performed worldwide. During this process, in addition to the chest, other tissues, including the thyroid, are also exposed to radiation. Due to the fact that one of the most important risk factors for thyroid cancer is ionizing radiation, measuring the absorption of X- rays in the thyroid is of spec...

Background: The number of interventional cardiology procedures performed has increased rapidly over the past years. While these procedures help physicians avoid using highly complicated invasive methods, it usually leads to high levels of exposure to ionizing radiation of both patients and cardiologist. The dose received by the cardiologist during interventional cardiology procedures is determi...

Introduction: Nowadays Intensity Modulated Radiotherapy (IMRT) is a common method for treating prostate cancers. Must of the Monte Carlo software cannot simulate the IMRT procedures due to inability of these soft wares to simulate the multi leaf collimator (MLC) positions or movements. A new user-friendly software based on the PENELOPE Monte Carlo code named PRIMO was published...
متن کاملEvaluation of organs at risk dose in the left breast IOERT procedures whit and without shielding disc using monte carlo simulation
Introduction: One of the treatment choices in breast cancer is Intra operative electron beam radiation therapy (IOERT). Due to high dose delivery in this procedure, shielding disk is used to protect organs at risk (OARs). In this study, we evaluate the OARs dose in the breast IOERT using Monte Carlo simulation with and without shielding disk in RANDO phantom. Material and Methods: Simulation ...
