Abstract

Раскрыт способ использования системы магнитометра для анализа магнитного поля области тела пациента. Способ содержит использование одного или более детекторов для обнаружения изменяющегося во времени магнитного поля области тела пациента, фильтрацию сигнала или сигналов от указанных одного или более детекторов при помощи фильтра или фильтров и использование фильтрованного сигнала или сигналов для анализа магнитного поля, создаваемого указанной областью тела пациента. При этом фильтр или фильтры выполняют с возможностью ослабления в сигнале или сигналах помехи, которая синхронизирована с движением рассматриваемой области тела пациента, например баллистокардиографической помехи.
