A dose ocupacional e a fluoroscopia pulsada no cateterismo cardíaco

Abstract

Catheterism in medical procedures is responsible for high X-ray doses, both to patients and medical staff. Aiming to reduce this dose, modern fluoroscopy equipment have been developed using pulsed X ray, but there is no agreement in the literature on the efficacy of these devices in reducing the dose. This study presents the results of measured occupational doses during simulated medical procedures, generated both for pulsed and continuous fluoroscopy, and the calculations allowing to quantify the reduction resulting by the use of pulsed technology. A mapping of radiation intensities was performed in the Laboratory in order to suggest better places (lower occupational doses) for personnel during medical procedures, and is presented as well. © 2013 Springer.
