MRI antennas including electrically connected inner and outer conductors, and MRI systems including such antennas

摘要

An MRI antenna comprises an inner conductor with first and second ends and an outer conductor with first and second ends. The outer conductor substantially surrounds the inner conductor. The inner and outer conductors define a region for receiving a body part and the inner conductor is electrically connected to the outer conductor. The inner and outer conductors may be connected in a variety of manners. For example, the inner conductor may be directly electrically connected to the outer conductor. The inner conductor may also be connected electrically to the outer conductor through one or more capacitors. A magnetic resonance imaging system including the antenna of the present invention is also disclosed.
