Estudo dosimétrico de pacientes em procedimentos de cardiologia intervencionista

Abstract

Interventional radiology is a real time image generation technique through the interaction of X-rays with matter. Interventional radiology uses, among others, the fluoroscopy technique to perform less invasive procedures, such as catheter insertion, organ function and blood flow analysis. Because it is an application of ionizing radiation, it is necessary to constantly monitor doses received by the patient, and clinical staff, during the procedures. Although the doses of radiation are low, the time of the examination directly influences the dose received. In this work, a bibliographic review on interventional radiology was carried out; in addition, a cardiology procedure was evaluated with Monte Carlo simulation, and the radiation doses were evaluated for both physician and patient.
