Abstract

CONJUNTO MAGNÉTICO DE GERAÇÃO DE IMAGENS POR RESSONÂNCIA MAGNÉTICA, SISTEMA DE GERAÇÃO DE IMAGENS POR RESSONÂNCIA E BOBINA DE GRADIENTE PARA A GERAÇÃO DE UM CAMPO MAGNÉTICO PARA UMA CODIFICAÇÃO ESPACIAL DAS ROTAÇÕES DOS NÚCLEOS NO INTERIOR DO VOLUME DE GERAÇÃO DE IMAGENS. Um conjunto magnético de geração de imagens por ressonância magnética (100) compreende: um ímã (102) adaptado para gerar um campo magnético principal para o alinhamento das rotações magnéticas dos núcleos de um indivíduo (502) localizado no interior de um volume de geração de imagens (504); e uma bobina de gradiente (103) para a geração de um campo magnético para uma codificação espacial do sinal de ressonância magnética das rotações dos núcleos no interior do volume de geração de imagens, em que a bobina de gradiente é adaptada para ser montada no ímã, em que a bobina de gradiente compreende: uma primeira seção da bobina de gradiente (112), em que a primeira seção da bobina de gradiente compreende um primeiro elemento rígido (113), uma segunda seção da bobina de gradiente (114), em que a segunda seção da bobina de gradiente também compreende um segundo elemento rígido (115), um elemento de conexão (116, 300, 302, 304, 400) para unir as duas metades das bobinas de gradiente, em que o elemento de conexão compreende um material elástico (116), em que o material elástico está em contato com o primeiro elemento rígido e o segundo elemento rígido.
