Abstract

várias modalidades incluem um método para configurar e gerar um pulso de saturação não adiabático para uso em perfilagem por ressonância magnética nuclear (nmr). um desses métodos configura o pulso, ajustando um ou mais dentre modulações de amplitude de pulso ou ciclo de fase. o pulso modificado é transmitido para um fluido de tal modo que uma resposta de eco de inversão de spin nuclear ou de saturação de spin nuclear substancialmente uniforme seja recebida do fluido. um tempo de espera entre a transmissão de pulso e a resposta de eco que indica que o equilíbrio do spin foi alcançado é substancialmente igual a um tempo t1. o tempo de espera é uma indicação das características do fluido.
