Abstract

sistema de ressonância magnética, monitor seguro depressão sanguínea para a mri, e, método para monitorar um objeto em um campo magnético na formação de imagens por ressonância magnética (mri), os poderosos campos magnéticos podem interferir com, danificar os, provocar falhas prematuras em, e atrair, certos instrumentos não-seguros da mr. a aliança de componentes eletromagnéticos sensitivos é eliminada em favor de componentes seguros para a mr, tais como os componentes de cerâmica piezelétrica e os componentes bimetálicos. os instrumentos, que anteriormente tinham que ser mantidos a uma distância segura do principal magneto (12) - de, por exemplo, mais de 5 da linha de gauss - enquanto o paciente era escaneado, podem agora ficar perto do paciente sem perigo de danificar o instrumento ( 40) e sem perigo para o paciente, para a equipe médica e para o dispositivo da mri (10).
