Abstract

resumo método de imageamento por rm, dispositivo de rm e programa de computador para ser executado em um dispositivo de rm a presente invenção se refere a um método de imageamento por rm paralelo, em que uma varredura de referência é executada por meio de uma sequência de eco estimulado incluindo: i) ao menos dois pulsos de rf de preparação (?) irradiados em direção a uma porção de um corpo (10) durante um período de preparação (21) e ii) um ou mais pulsos de rf de leitura (?) irradiados em direção à porção do corpo (10) durante um período de captura (22) temporalmente subsequente ao período de preparação (21). um ou mais sinais fid (i1) e um ou mais sinais de eco estimulado (i2) são capturados durante o período de captura (22). os perfis de sensibilidade de recebimento e/ou, se aplicável, de transmissão espacial de pelo menos duas bobinas de rf (11, 12, 13) são derivados dos sinais fid capturados (i1) e/ou dos sinais de eco estimulado capturados (i2). os parâmetros da sequência de eco estimulado são selecionados de tal modo que ela seja resistente contra artefatos induzidos por susceptibilidade. além disso, a invenção se refere a um dispositivo de rm (1) e a um programa de computador para um dispositivo de rm (1). 1/1
