Abstract
um método para processar os dados de medição de ressonância magnética nuclear (rmn) inclui receber, com um processador, os dados de medição de rmn obtidos de uma ferramenta de rmn, os dados de medição de rmn tendo um trem de eco afetado por um artefato de movimento, em que o artefato de movimento está relacionado a uma magnitude de campo magnético que varia em um volume de interesse devido a um movimento da ferramenta de rmn. o método inclui ainda reduzir, com o processador, um efeito nos dados de medição de rmn do artefato de movimento usando um método de inversão de correção que modela o artefato de movimento para fornecer uma distribuição de constante de tempo de relaxamento transversal corrigida (t2), em que o método de inversão de correção tem um termo multiplicativo que tem um termo inclui pelo menos um máximo local e um termo de decaimento opcional.
