Abstract

resumo antena de transmissão e/ou recebimento de rf/rm multirressonante ou de ressonância dupla; e aparelho ou sistema de geração de imagem de rm uma antena de transmissão e/ou recebimento de rf/rm multirressonante ou de ressonância dupla (1, 2) especialmente na forma de uma antena planar ou antena de volume em agrupamento (também chamada de conjunto de antena) é descrita para geração de imagem de rm de pelo menos dois núcleos diferentes, como, por exemplo, 1h, 19f, 3he, 13c, 23na ou outros núcleos com frequências de larmor diferentes. basicamente, a antena é acoplada por meio de um dispositivo de acoplamento indutivo (l1) com canais de transmissão/recebimento relacionados (t/r). por meio de tal acoplamento indutivo, o ajuste e a correspondência da antena nas frequências de ressonância diferentes são mais fáceis de serem obtidos do que no caso de uma conexão galvânica. além disso, a invenção se refere a um aparelho de geração de imagem de rm compreendendo tal antena de transmissão e/ou recebimento de rf/rm multirressonante ou de ressonância dupla.
