Abstract(s)
Nos últimos anos, a importância da radiação ionizante na prática médica, utilizada não
só para o diagnóstico como para a terapia, ganhou uma importância fulcral. Devido aos
efeitos secundários da radiação ao ser humano, torna-se fundamental aumentar a segurança
de todos os seus utilizadores.
O objetivo deste trabalho recai na aquisição de leituras de dispositivos medidores de
atividades de radionuclídeos (calibradores de dose), que posteriormente irão comunicar
a um protótipo de um sistema robótico, que permite reduzir a exposição à radiação por
parte dos profissionais de saúde, que desenvolvem a sua atividade na área da Medicina
Nuclear.
Para concretizar estes objetivos foi desenvolvida uma aplicação computacional capaz de
registar as leituras de atividade medidas pelo calibrador de dose de um estudo de um
paciente e guardá-los numa base de dados. Estes dados são validados com a aplicação
de um programa de controlo de qualidade aos dispositivos de leitura, por forma a mensurar
o erro associado comunicado ao protótipo.
Os resultados são animadores uma vez que foram realizados testes de utilização e comunicação
da aplicação desenvolvida, verificando a sua operacionalidade no dia-a-dia
num serviço de medicina nuclear.
In last few years, the importance of ionizing radiation in medical practice, used not only in diagnosis but also in therapy, gained a central importance. Due to the side effects of radiation upon human beings, it becomes important to increase the security of all its users. The aim of this work is to acquire radionuclides activity readings from measuring devices (dose calibrator), that will posteriorly communicate to a prototype of a robotic system, which allows the reduction of the health professional’s exposure to radiation who develop their occupation in Nuclear Medicine. To reach these targets, a computational application was developed which is capable of registering the activity readings measured by the dose calibrator of a study of a patient and save them in a data base. These data are validated by the application of a quality control program to the dose calibrators in a way that measures the associated error communicated to the prototype. The results obtained are encouraging since tests have been performed on the use and communication of the application developed, verifying its day to day operability in a nuclear medicine service.
