PET Positron Emission Tomography – Electrónica de Front-End
Edgar Francisco Monteiro Albuquerque,
Inesc-ID –
Abstract:
Instrumentação para medicina é um campo relativamente novo na engenharia e de crescimento muito rápido decorrente dos avanços na última década nas áreas da microelectrónica e particularmente na área dos sensores de estado sólido. Com a finalidade de aproveitar estes novos desenvolvimentos bem como competências, conhecimento e outras sinergias existente em instituições nacionais, foi criado em Dezembro de 2002 o Consortium PET – Mammography liderado pelo LIP, Laboratório de Física de Partículas e constituído por sete instituições nacionais especializadas nas áreas de medicina nuclear, física dos detectores de radiação, biofísica, engenharia médica , electrónica, computação e engenharia mecânica, entre as quais o INESC-ID/INOV. Coube ao INESC-ID/INOV o desenvolvimento dos sistemas electrónicos necessários, e, nomeadamente, ao Grupo de Circuito Analógicos e Mistos o desenvolvimento de circuito integrado para processamento dos sinais provenientes dos sensores, circuito designado por Front-End ASIC. Neste seminário apresentam-se os requisitos para o Front-End ASIC, e a arquitectura proposta. Apresentam-se ainda os blocos desenvolvidos que compõem o sistema, nomeadamente: amplificador, comparador de elevada precisão, memórias analógicas, multiplexers analógicos e controlador do sistema. São apresentados os protótipos fabricados bem como os respectivos resultados dos ensaios laboratoriais. São ainda apresentadas as dificuldades encontradas em integrar um sistemas misto analógico/digital de elevado desempenho deste tipo, contendo blocos analógicos de elevada precisão e digitais operando a frequências elevadas. Por fim analisa-se o estado actual do projecto sendo enumeradas as tarefas ainda a realizar e é apontado o trabalho a realizar no futuro próximo bem como as lições aprendidas no decurso deste projecto.
