Катрен СтильУченые изобрели перчатку для МРТ, способную сканировать в движении
Инженеры с медицинского факультета Нью-Йоркского университета (New York University School of Medicine) создали устройство для проведения магнитно-резонансной томографии руки во время движения. Статья с подробным описанием изобретения опубликована в журнале Nature 4 мая.
Обычно проведение сканирования с помощью МРТ требует фиксации части тела в определенном положении в течение всей процедуры. Это связано с тем, что для точности измерений электромагнитные катушки должны быть расположены на строго фиксируемом взаимном расстоянии, что позволяет избежать влияния магнитных полей катушек друг на друга.
В своем изобретении ученые использовали электромагнитные катушки с высоким импедансом, а не низким, как в традиционных аппаратах МРТ. В результате им удалось избежать влияния магнитных полей на соседние детекторы. Таким образом получилось создать подвижную конструкцию из датчиков, которые были прикреплены к обычной хлопчатобумажной перчатке.
Результаты испытаний показали, что прибор позволяет получать точные трехмерные изображения мягких тканей во время движения кисти и пальцев. МРТ-перчатку проверяли во время работы за компьютером и игры на пианино. Точность показаний устройства практически не отличалась от других приборов для МРТ, требующих фиксации кисти.
Авторы изобретения признают, что устройство пока представляет собой прототип, но отмечают, что оно является первым сканером, который обладает достаточной чувствительностью диагностики и подвижностью, чтобы проводить сканирование мягких тканей во время их движения. В будущем такие разработки смогут применяться для диагностики и исследования различных хронических болезней кисти.
