Abstract
ANTENA DE RF DE TRANSMISSÃO E/OU RECEPÇÃO E SISTEMA IRM OU SCANNER RM. Antena de RF de transmissão e /ou recepção é apresentada, especialmente sob a forma de uma estrutura de bobina ou disposição da bobina ou presilha, tendo um ou mais condutores removíveis, especialmente para uso em um sistema de imagem de ressonância magnética (IRM) ou um scanner de ressonância magnética (RM), para a transmissão de sinais de estimulo RF (campo B;) para estimular ressonâncias magnéticas nucleares (RMN), e/ou receber sinais de relaxamento de RMN. A antena de RF é fornecida de modo a ser adaptada de um modo fácil de acordo com uma aplicação que requeira uma grande abertura através da antena de RF ou uma capacidade de imagens em paralelo.
