Abstract

Раскрыт способ использования системы магнитометра для анализа магнитного поля области тела пациента. Способ содержит получение одного или более сигналов, соответствующих производной по времени от изменяющегося во времени магнитного поля области тела пациента; усреднение сигнала или сигналов производной по времени за множество периодов и использование усредненных сигнала или сигналов производной по времени для анализа магнитного поля, создаваемого определенной областью тела пациента.
