Abstract

Реализуемый компьютером способ позволяет получать распределение плотности протонов. В одном осуществлении способ содержит регистрацию данных ядерно-магнитного резонанса из пористых сред; обращение данных ядерно-магнитного резонанса с помощью алгоритма глобальной оптимизации для определения распределения плотности протонов в пористых средах и вывод определенного распределения плотности протонов.
