Ultrassonografia: Princípios Físicos e Controle da Qualidade

Abstract

Neste artigo fazemos uma breve revisão da ultrassonografia na perspectiva da física médica. Iniciamos apresentando uma visão resumida dos princípios físicos mais fundamentais em imagens por ultrassom e alguns parâmetros importantes na aferição da qualidade de imagem e do desempenho geral dos ecógrafos que derivam desses princípios. Na segunda parte, apresentamos uma contextualização histórica do controle da qualidade (CQ) em ultrassonografia na prática profissional da física médica e as dificuldades associadas à falta de legislação governamental e à contínua evolução da tecnológica. Esforços para sistematizar e implementar protocolos de CQ para ultrassonografia no Brasil são feitos há mais de 20 anos. Porém, que nível de inserção nesse mercado tão amplo foi atingido pelos serviços e empresas de física médica desde então? Fazemos uma breve reflexão sobre essa questão a partir da experiência no estado do Rio Grande do Sul, buscando, ao final, extrapolar para o cenário nacional e avaliar as perspectivas futuras do CQ no mercado da física médica.
