Abstract

Медицинский магнитометр (10), содержащий одну или более катушек (2) индуктивности для детектирования переменного во времени магнитного поля области тела исследуемого субъекта, например сердца. Единственная или каждая катушка имеет максимальный наружный диаметр, составляющий 4-7 см, и конфигурацию, при которой отношение ее длины к наружному диаметру составляет по меньшей мере 0,5, а отношение ее внутреннего диаметра к ее наружному диаметру составляет 0,5 или менее. При этом каждая катушка (2) индуктивности подключена к детекторному контуру, содержащему низкоимпедансный предусилитель (3), фильтр (5) нижних частот, узкополосный режекторный фильтр (6) для подавления шума в линии питания и усредняющий элемент (7). Каждый детекторный контур формирует выходной сигнал (9) для использования при анализе переменного во времени магнитного поля области тела исследуемого субъекта.
